4bf17af Jan Kara 14 July 2009, 17:30:23 UTC udf: Fix loading of VAT inode when drive wrongly reports number of recorded blocks VAT inode is located in the last block recorded block of the medium. When the drive errorneously reports number of recorded blocks, we failed to load the VAT inode and thus mount the medium. This patch makes kernel try to read VAT inode from the last block of the device if it is different from the last recorded block. Signed-off-by: Jan Kara <jack@suse.cz> 30 July 2009, 15:28:26 UTC
b94a170 Benjamin Marzinski 23 July 2009, 23:52:34 UTC GFS2: remove dcache entries for remote deleted inodes When a file is deleted from a gfs2 filesystem on one node, a dcache entry for it may still exist on other nodes in the cluster. If this happens, gfs2 will be unable to free this file on disk. Because of this, it's possible to have a gfs2 filesystem with no files on it and no free space. With this patch, when a node receives a callback notifying it that the file is being deleted on another node, it schedules a new workqueue thread to remove the file's dcache entry.

6b94617 Benjamin Marzinski 10 July 2009, 23:13:26 UTC GFS2: Fix incorrent statfs consistency check Since both linked and unlinked inodes are counted by rgd->rd_dinodes, It makes no sense to count them with the used data blocks (first check that I changed), it makes sense to count them with the linked inodes (second check), and it makes no sense to care if there are more unlinked inodes than linked ones. This fixes these errors. Signed-off-by: Benjamin Marzinski <bmarzins@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com> 30 July 2009, 10:00:28 UTC
8ff22a6 Benjamin Marzinski 10 July 2009, 23:04:24 UTC GFS2: Don't put unlikely reclaim candidates on the reclaim list. GFS2 was placing far too many glocks on the reclaim list that were not good candidates for freeing up from cache. These locks would sit there and repeatedly get scanned to see if they could be reclaimed, wasting a lot of time when there was memory pressure. This fix does more checks on the locks to see if they are actually likely to be removable from cache.

1e19a19 Steven Whitehouse 10 July 2009, 20:13:38 UTC GFS2: Don't try and dealloc own inode When searching for unlinked, but still allocated inodes during block allocation, avoid the block relating to the inode that is doing the allocation. This fixes a hang caused when an unlinked, but still open, inode tries to allocate some more blocks and lands up finding itself during the search for deallocatable inodes.

a51b56f Benjamin Marzinski 30 June 2009, 18:51:11 UTC GFS2: Fix panic in glock memory shrinker It is possible for gfs2_shrink_glock_memory() to check a glock for demotion that's in the process of being freed by gfs2_glock_put(). In this case, gfs2_shrink_glock_memory() will acquire a new reference to this glock, and then try to free the glock itself when it drops the refernce. To solve this, gfs2_shrink_glock_memory() just needs to check if the glock is in the process of being freed, and if so skip it without ever unlocking the lru_lock.

1946f70 Benjamin Marzinski 25 June 2009, 20:09:51 UTC GFS2: keep statfs info in sync on grows GFS2 wasn't syncing its statfs info on grows. This causes a problem when you grow the filesystem on multiple nodes. GFS2 would calculate the new space based on the resource groups (which are always current), and then assume that the filesystem had grown the from the existing statfs size. If you grew the filesystem on two different nodes in a short time, the second node wouldn't see the statfs size change from the first node, and would assume that it was grown by a larger amount than it was. When all these changes were synced out, the total fileystem size would be incorrect (the first grow would be counted twice). This patch syncs makes GFS2 read in the statfs changes from disk before a grow, and write them out after the grow, while the master statfs inode is locked.

2163b1e Steven Whitehouse 25 June 2009, 15:30:26 UTC GFS2: Shrink the shrinker This patch removes some of the special cases that the shrinker was trying to deal with. As a result we leave fewer items on the list and none at all which cannot be demoted. This makes the list scanning more efficient and solves some issues seen with large numbers of inodes.

This is because U-Boot wrongly clears interrupt polarity bit (INTPOL, 0x400) in the extended status register (EXT_SR, 0x1b) of Marvell PHYs. There is no easy way for PHY drivers to know IRQ line polarity (we could extract it from the device tree and pass it to phydevs, but that'll be quite a lot of work), so for now just reset the PHYs to their default states.

534acc0 Dave Hansen 29 July 2009, 22:04:18 UTC lib: flexible array implementation Once a structure goes over PAGE_SIZE*2, we see occasional allocation failures. Some people have chosen to switch over to things like vmalloc() that will let them keep array-like access to such a large structures. But, vmalloc() has plenty of downsides. Here's an alternative. I think it's what Andrew was suggesting here: http://lkml.org/lkml/2009/7/2/518 I call it a flexible array. It does all of its work in PAGE_SIZE bits, so never does an order>0 allocation. The base level has PAGE_SIZE-2*sizeof(int) bytes of storage for pointers to the second level. So, with a 32-bit arch, you get about 4MB (4183112 bytes) of total storage when the objects pack nicely into a page. It is half that on 64-bit because the pointers are twice the size. There's a table detailing this in the code. There are kerneldocs for the functions, but here's an overview: flex_array_alloc() - dynamically allocate a base structure flex_array_free() - free the array and all of the second-level pages flex_array_free_parts() - free the second-level pages, but not the base (for static bases) flex_array_put() - copy into the array at the given index flex_array_get() - copy out of the array at the given index flex_array_prealloc() - preallocate the second-level pages between the given indexes to guarantee no allocs will occur at put() time. We could also potentially just pass the "element_size" into each of the API functions instead of storing it internally. That would get us one more base pointer on 32-bit. I've been testing this by running it in userspace. The header and patch that I've been using are here, as well as the little script I'm using to generate the size table which goes in the kerneldocs. http://sr71.net/~dave/linux/flexarray/ [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Dave Hansen <dave@linux.vnet.ibm.com> Reviewed-by: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 30 July 2009, 02:10:36 UTC
a9e58f2 Anton Vorontsov 29 July 2009, 22:04:16 UTC sdhci: get rid of "frequency too high" flood when using eSDHC Since commit 8dfd0374be84793360db7fff2e635d2cd3bbcb21 ("MMC core: limit minimum initialization frequency to 400kHz") MMC core checks for minimum frequency, and that causes following messages flood when using eSDHC controllers: ... mmc0: Minimum clock frequency too high for identification mode mmc0: Minimum clock frequency too high for identification mode ... The warnings are legitimate, since if we'd use 133 MHz clocks for standard SDHCI controllers, we'd not able to scale frequency down to 400 kHz. But eSDHC controllers have a non-standard SD clock management, so we can divide clock by 256 * 16, not just 256. This patch introduces get_min_clock() callback for sdhci core and implements it for sdhci-of driver, and thus fixes the issue.

cab8bd3 Hidetoshi Seto 29 July 2009, 22:04:14 UTC sysrq, kdump: make sysrq-c consistent commit d6580a9f15238b87e618310c862231ae3f352d2d ("kexec: sysrq: simplify sysrq-c handler") changed the behavior of sysrq-c to unconditional dereference of NULL pointer. So in cases with CONFIG_KEXEC, where crash_kexec() was directly called from sysrq-c before, now it can be said that a step of "real oops" was inserted before starting kdump. However, in contrast to oops via SysRq-c from keyboard which results in panic due to in_interrupt(), oops via "echo c > /proc/sysrq-trigger" will not become panic unless panic_on_oops=1. It means that even if dump is properly configured to be taken on panic, the sysrq-c from proc interface might not start crashdump while the sysrq-c from keyboard can start crashdump. This confuses traditional users of kdump, i.e. people who expect sysrq-c to do common behavior in both of the keyboard and proc interface. This patch brings the keyboard and proc interface behavior of sysrq-c in line, by forcing panic_on_oops=1 before oops in sysrq-c handler. And some updates in documentation are included, to clarify that there is no longer dependency with CONFIG_KEXEC, and that now the system can just crash by sysrq-c if no dump mechanism is configured.

We cache a pid array for all threads that are opening the same "tasks" file, but the pids in the array are always from the namespace of the last process that opened the file, so all other threads will read pids from that namespace instead of their own namespaces. To fix it, we maintain a list of pid arrays, which is keyed by pid_ns. The list will be of length 1 at most time.

This is a regression from commit a5516438959d90b071ff0a484ce4f3f523dc3152 ("hugetlb: modular state for hugetlb page size") which did: - inode->i_blocks -= BLOCKS_PER_HUGEPAGE * freed; + inode->i_blocks -= blocks_per_huge_page(h); so just put back the freed multiplier, and it's all happy again.

933b787 Rik van Riel 29 July 2009, 22:02:07 UTC mm: copy over oom_adj value at fork time Fix a post-2.6.31 regression which was introduced by 2ff05b2b4eac2e63d345fc731ea151a060247f53 ("oom: move oom_adj value from task_struct to mm_struct"). After moving the oom_adj value from the task struct to the mm_struct, the oom_adj value was no longer properly inherited by child processes. Copying over the oom_adj value at fork time fixes that bug.

6583bb6 David Rientjes 29 July 2009, 22:02:06 UTC mm: avoid endless looping for oom killed tasks If a task is oom killed and still cannot find memory when trying with no watermarks, it's better to fail the allocation attempt than to loop endlessly. Direct reclaim has already failed and the oom killer will be a no-op since current has yet to die, so there is no other alternative for allocations that are not __GFP_NOFAIL.

e084b2d Mel Gorman 29 July 2009, 22:02:04 UTC page-allocator: preserve PFN ordering when __GFP_COLD is set Fix a post-2.6.24 performace regression caused by 3dfa5721f12c3d5a441448086bee156887daa961 ("page-allocator: preserve PFN ordering when __GFP_COLD is set"). Narayanan reports "The regression is around 15%. There is no disk controller as our setup is based on Samsung OneNAND used as a memory mapped device on a OMAP2430 based board." The page allocator tries to preserve contiguous PFN ordering when returning pages such that repeated callers to the allocator have a strong chance of getting physically contiguous pages, particularly when external fragmentation is low. However, of the bulk of the allocations have __GFP_COLD set as they are due to aio_read() for example, then the PFNs are in reverse PFN order. This can cause performance degration when used with IO controllers that could have merged the requests. This patch attempts to preserve the contiguous ordering of PFNs for users of __GFP_COLD.

This change makes the driver register a bit earlier which together with earlier platform data moves the time for probe(). The earlier probe() makes it possible to use i2c_get_adapter() and i2c_transfer() from device_initcall(). The same strategy is used by other i2c bus drivers such as i2c-pxa.c and i2c-s3c2410.c.

e043e42 OGAWA Hirofumi 29 July 2009, 19:15:56 UTC pty: avoid forcing 'low_latency' tty flag We really don't want to mark the pty as a low-latency device, because as Alan points out, the ->write method can be called from an IRQ (ppp?), and that means we can't use ->low_latency=1 as we take mutexes in the low_latency case. So rather than using low_latency to force the written data to be pushed to the ldisc handling at 'write()' time, just make the reader side (or the poll function) do the flush when it checks whether there is data to be had. This also fixes the problem with lost data in an emacs compile buffer (bugzilla 13815), and we can thus revert the low_latency pty hack (commit 3a54297478e6578f96fd54bf4daa1751130aca86: "pty: quickfix for the pty ENXIO timing problems").

dddac6a Alan Jenkins 29 July 2009, 19:07:55 UTC PM / Hibernate: Replace bdget call with simple atomic_inc of i_count Create bdgrab(). This function copies an existing reference to a block_device. It is safe to call from any context. Hibernation code wishes to copy a reference to the active swap device. Right now it calls bdget() under a spinlock, but this is wrong because bdget() can sleep. It doesn't need a full bdget() because we already hold a reference to active swap devices (and the spinlock protects against swapoff).
