Chop it down to something reasonable, the number of slots in the caller's input buffer. If this is too large the caller may get ENOMEM but the reason should not be a mystery, and they can try again with something smaller. We add 1 to the value because in the normal getbmap world, bmv_count includes the header and xfs_getbmap does: nex = bmv->bmv_count - 1; if (nex <= 0) return XFS_ERROR(EINVAL); Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Reviewed-by: Olaf Weber <olaf@sgi.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Felix Blyakher <felixb@sgi.com>31 July 2009, 05:56:58 UTC

This copy of the tree root isn't going to change and it significantly reduces the complexity of the scanning code. During a commit, we have a loop where we update the extent allocation tree root. We need to loop because updating the root pointer in the tree of tree roots may allocate blocks which may change the extent allocation tree. Right now the commit_root pointer is changed inside this loop. It is more correct to change the commit_root pointer only after all the looping is done.

b94a170 Benjamin Marzinski23 July 2009, 23:52:34 UTCGFS2: 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.

GFS2 was placing far too many glocks on the reclaim list that were not good candidates for freeing up from cache.

a51b56f Benjamin Marzinski30 June 2009, 18:51:11 UTCGFS2: 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 Marzinski25 June 2009, 20:09:51 UTCGFS2: 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.

534acc0 Dave Hansen29 July 2009, 22:04:18 UTClib: 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 Vorontsov29 July 2009, 22:04:16 UTCsdhci: 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 Seto29 July 2009, 22:04:14 UTCsysrq, 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.

1fc28b7 Mel Gorman29 July 2009, 22:04:08 UTCpage-allocator: allow too high-order warning messages to be suppressed with __GFP_NOWARN The page allocator warns once when an order >= MAX_ORDER is specified. This is to catch callers of the allocator that are always falling back to their worst-case when it was not expected. However, there are cases where the caller is behaving correctly but cannot suppress the warning. This patch allows the warning to be suppressed by the callers by specifying __GFP_NOWARN.

8870326 KAMEZAWA Hiroyuki29 July 2009, 22:04:06 UTCcgroup avoid permanent sleep at rmdir After commit ec64f51545fffbc4cb968f0cea56341a4b07e85a ("cgroup: fix frequent -EBUSY at rmdir"), cgroup's rmdir (especially against memcg) doesn't return -EBUSY by temporary ref counts. That commit expects all refs after pre_destroy() is temporary but...it wasn't. Then, rmdir can wait permanently. This patch tries to fix that and change followings. - set CGRP_WAIT_ON_RMDIR flag before pre_destroy(). - clear CGRP_WAIT_ON_RMDIR flag when the subsys finds racy case. if there are sleeping ones, wakes them up. - rmdir() sleeps only when CGRP_WAIT_ON_RMDIR flag is set.

f0d8367 Sebastian Heutling29 July 2009, 22:04:05 UTCeeprom/at25: bugfix "not ready" timeout after write Under certain circumstances msleep(1) within the loop, which waits for the EEPROM to be finished, might take longer than the timeout. On the next loop the status register might now return to be ready and therefore the loop finishes. The following check now tests if a timeout occurred and if so returns an error although the device reported it was ready. This fix replaces testing the occurrence of the timeout by testing the "not ready" bit in the status register.

096b7fe Li Zefan29 July 2009, 22:04:04 UTCcgroups: fix pid namespace bug The bug was introduced by commit cc31edceee04a7b87f2be48f9489ebb72d264844 ("cgroups: convert tasks file to use a seq_file with shared pid array"). 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.

3fc7b4b Roland Dreier29 July 2009, 22:04:02 UTClib: export generic atomic64_t functions The generic atomic64_t implementation in lib/ did not export the functions it defined, which means that modules that use atomic64_t would not link on platforms (such as 32-bit powerpc). For example, trying to build a kernel with CONFIG_NET_RDS on such a platform would fail with: ERROR: "atomic64_read" [net/rds/rds.ko] undefined! ERROR: "atomic64_set" [net/rds/rds.ko] undefined! Fix this by exporting the atomic64_t functions to modules.

e4c6f8b Eric Sandeen29 July 2009, 22:02:16 UTChugetlbfs: fix i_blocks accounting As reported in Red Hat bz #509671, i_blocks for files on hugetlbfs get accounting wrong when doing something like: $ > foo $ date > foo date: write error: Invalid argument $ /usr/bin/stat foo File: `foo' Size: 0 Blocks: 18446744073709547520 IO Block: 2097152 regular ... This is because hugetlb_unreserve_pages() is unconditionally removing blocks_per_huge_page(h) on each call rather than using the freed amount. If there were 0 blocks, it goes negative, resulting in the above. 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.

When PNP has not succeeded probing, platform is registered. However, it tries to unregister both drivers unconditionally, instead of only unregistering those that were successfully registered. This causes runtime warnings to be emitted from the driver core code. Fix this with a boolean variable for each driver indicating whether registering was successful.
