3419c75 Alex Chiang 28 January 2009, 21:59:18 UTC PCI: properly clean up ASPM link state on device remove We only want to disable ASPM when the last function is removed from the parent's device list. We determine this by checking to see if the parent's device list is completely empty. Unfortunately, we never hit that code because the parent is considered an upstream port, and never had an ASPM link_state associated with it. The early check for !link_state causes us to return early, we never discover that our device list is empty, and thus we never remove the downstream ports' link_state nodes. Instead of checking to see if the parent's device list is empty, we can check to see if we are the last device on the list, and if so, then we know that we can clean up properly.

dcf6a79 Artem Bityutskiy 02 February 2009, 16:33:49 UTC write-back: fix nr_to_write counter Commit 05fe478dd04e02fa230c305ab9b5616669821dd3 introduced some @wbc->nr_to_write breakage. It made the following changes: 1. Decrement wbc->nr_to_write instead of nr_to_write 2. Decrement wbc->nr_to_write _only_ if wbc->sync_mode == WB_SYNC_NONE 3. If synced nr_to_write pages, stop only if if wbc->sync_mode == WB_SYNC_NONE, otherwise keep going. However, according to the commit message, the intention was to only make change 3. Change 1 is a bug. Change 2 does not seem to be necessary, and it breaks UBIFS expectations, so if needed, it should be done separately later. And change 2 does not seem to be documented in the commit message. This patch does the following: 1. Undo changes 1 and 2 2. Add a comment explaining change 3 (it very useful to have comments in _code_, not only in the commit).

9b02605 David S. Miller 04 February 2009, 00:28:23 UTC sparc64: Kill bogus TPC/address truncation during 32-bit faults. This builds upon eeabac7386ca13bfe1a58afeb04326a9e1a3a20e ("sparc64: Validate kernel generated fault addresses on sparc64.") Upon further consideration, we actually should never see any fault addresses for 32-bit tasks with the upper 32-bits set. If it does every happen, by definition it's a bug. Whatever context created that fault would only have that fault satisfied if we used the full 64-bit address. If we truncate it, we'll always fault the wrong address and we'll always loop faulting forever. So catch such conditions and mark them as errors always. Log the error and fail the fault.

eeabac7 David S. Miller 03 February 2009, 06:08:15 UTC sparc64: Validate kernel generated fault addresses on sparc64. In order to handle all of the cases of address calculation overflow properly, we run sparc 32-bit processes in "address masking" mode when running on a 64-bit kernel. Address masking mode zeros out the top 32-bits of the address calculated for every load and store instruction. However, when we're in privileged mode we have to run with that address masking mode disabled even when accessing userspace from the kernel. To "simulate" the address masking mode we clear the top-bits by hand for 32-bit processes in the fault handler. It is the responsibility of code in the compat layer to properly zero extend addresses used to access userspace. If this isn't followed properly we can get into a fault loop. Say that the user address is 0xf0000000 but for whatever reason the kernel code sign extends this to 64-bit, and then the kernel tries to access the result. In such a case we'll fault on address 0xfffffffff0000000 but the fault handler will process that fault as if it were to address 0xf0000000. We'll loop faulting forever because the fault never gets satisfied. So add a check specifically for this case, when the kernel is faulting on a user address access and the addresses don't match up. This code path is sufficiently slow path, and this bug is sufficiently painful to diagnose, that this kind of bug check is warranted. Signed-off-by: David S.

Evidence of processing timer interrupts is what the NMI watchdog uses to determine if the CPU is stuck. On Niagara, we'll yield the cpu. This will make the cpu, at worst, hang out in the hypervisor until an interrupt arrives. This will prevent the NMI watchdog timer from firing. However on non-Niagara we just loop executing instructions which will cause the NMI watchdog to keep firing. It won't see timer interrupts happening so it will think the cpu is stuck. Fix this by touching the NMI watchdog in the cpu idle loop on non-Niagara machines. Signed-off-by: David S. Miller <davem@davemloft.net> 03 February 2009, 05:57:48 UTC

It's usually okay to let EH handle speed down after transmission failures but some WD My Book drives completely shutdown after certain transmission failures and after it only power cycling can revive them. Combined with the fact that external drives often end up with cable assembly which is longer than usual and more likely to have intervening gender, this makes these drives very likely to shutdown under certain configurations virtually rendering them unusable. This patch implements HOARKGE_1_5_GBPS and applies it to WD My Book such that 1.5Gbps is forced once the device is identified.

c2c7a89 Tejun Heo 29 January 2009, 11:31:34 UTC libata: improve probe failure handling When link is flaky at high speed, it isn't uncommon for a device to repeatedly fail probing sequence early after successfully negotiating high link speed. This often leads to consecutive hotplug events without successful probing. This patch improves libata EH such that it remembers probing trials and if there have been more than two unsuccessful trials in the past 60 seconds, slows down link speed to 1.5Gbps. As link speed negotiation is the duty of the PHY layer proper, the goal of this fallback mechanism is to provide the last resort when everything else fails, which unfortunately happens not too infrequently, so no fancy 6->3->1.5 speeding down or highest successful transmission speed seen kind of logics (yet).

This patch achieves this by doing the following. * Instead of CLEAR_OFFSET, define CLEAR_BEGIN and CLEAR_END and only clear between BEGIN and END. ering is moved after END. The split of persistent area is to allow hotter items remain at the head. * ering is explicitly cleared on ata_dev_disable() and when device attach succeeds. So, ering is persistent throug a device's life time (unless explicitly cleared of course) and also through periods inbetween disablement of an attached device and successful detection of the next one.

3fff017 Mark McLoughlin 03 February 2009, 03:03:53 UTC virtio-pci: do not oops on config change if driver not loaded The host really shouldn't be notifying us of config changes before the device status is VIRTIO_CONFIG_S_DRIVER or VIRTIO_CONFIG_S_DRIVER_OK. However, if we do happen to be interrupted while we're not attached to a driver, we really shouldn't oops. Prevent this simply by checking that device->driver is non-NULL before trying to notify the driver of config changes. Problem observed by doing a "set_link virtio.0 down" with QEMU before the net driver had been loaded.

720eba3 Eric Dumazet 03 February 2009, 03:01:36 UTC modules: Use a better scheme for refcounting Current refcounting for modules (done if CONFIG_MODULE_UNLOAD=y) is using a lot of memory. Each 'struct module' contains an [NR_CPUS] array of full cache lines. This patch uses existing infrastructure (percpu_modalloc() & percpu_modfree()) to allocate percpu space for the refcount storage. Instead of wasting NR_CPUS*128 bytes (on i386), we now use nr_cpu_ids*sizeof(local_t) bytes. On a typical distro, where NR_CPUS=8, shiping 2000 modules, we reduce size of module files by about 2 Mbytes. (1Kb per module) Instead of having all refcounters in the same memory node - with TLB misses because of vmalloc() - this new implementation permits to have better NUMA properties, since each CPU will use storage on its preferred node, thanks to percpu storage.

fd4ef23 Mark Fasheh 29 January 2009, 23:06:21 UTC ocfs2: add quota call to ocfs2_remove_btree_range() We weren't reclaiming the clusters which get free'd from this function, so any user punching holes in a file would still have those bytes accounted against him/her. Add the call to vfs_dq_free_space_nodirty() to fix this. Interestingly enough, the journal credits calculation already took this into account.

a4b9196 Sunil Mushran 30 January 2009, 01:12:31 UTC ocfs2: Wakeup the downconvert thread after a successful cancel convert When two nodes holding PR locks on a resource concurrently attempt to upconvert the locks to EX, the master sends a BAST to one of the nodes. This message tells that node to first cancel convert the upconvert request, followed by downconvert to a NL. Only when this lock is downconverted to NL, can the master upconvert the first node's lock to EX. While the fs was doing the cancel convert, it was forgetting to wake up the dc thread after a successful cancel, leading to a deadlock.

In ocfs2_xattr_value_truncate, we may call b-tree codes which will extend the journal transaction. It has a potential problem that it may let the already-accessed-but-not-dirtied buffers gone. So we'd better access the bucket after we call ocfs2_xattr_value_truncate. And as for the root buffer for the xattr value, b-tree code will acess and dirty it, so we don't need to worry about it.

0e03334 Joel Becker 17 December 2008, 22:23:52 UTC configfs: Silence lockdep on mkdir(), rmdir() and configfs_depend_item() When attaching default groups (subdirs) of a new group (in mkdir() or in configfs_register()), configfs recursively takes inode's mutexes along the path from the parent of the new group to the default subdirs. This is needed to ensure that the VFS will not race with operations on these sub-dirs. This is safe for the following reasons: - the VFS allows one to lock first an inode and second one of its children (The lock subclasses for this pattern are respectively I_MUTEX_PARENT and I_MUTEX_CHILD); - from this rule any inode path can be recursively locked in descending order as long as it stays under a single mountpoint and does not follow symlinks. Unfortunately lockdep does not know (yet?) how to handle such recursion. I've tried to use Peter Zijlstra's lock_set_subclass() helper to upgrade i_mutexes from I_MUTEX_CHILD to I_MUTEX_PARENT when we know that we might recursively lock some of their descendant, but this usage does not seem to fit the purpose of lock_set_subclass() because it leads to several i_mutex locked with subclass I_MUTEX_PARENT by the same task. >From inside configfs it is not possible to serialize those recursive locking with a top-level one, because mkdir() and rmdir() are already called with inodes locked by the VFS. So using some mutex_lock_nest_lock() is not an option. I am proposing two solutions: 1) one that wraps recursive mutex_lock()s with lockdep_off()/lockdep_on(). 2) (as suggested earlier by Peter Zijlstra) one that puts the i_mutexes recursively locked in different classes based on their depth from the top-level config_group created. This induces an arbitrary limit (MAX_LOCK_DEPTH - 2 == 46) on the nesting of configfs default groups whenever lockdep is activated but this limit looks reasonably high. Unfortunately, this alos isolates VFS operations on configfs default groups from the others and thus lowers the chances to detect locking issues. This patch implements solution 1). Solution 2) looks better from lockdep's point of view, but fails with configfs_depend_item(). This needs to rework the locking scheme of configfs_depend_item() by removing the variable lock recursion depth, and I think that it's doable thanks to the configfs_dirent_lock. For now, let's stick to solution 1).

In such case ocfs2_write_dquot() must not try to sync the dquot because that needs global quota lock but that ranks above transaction start.

This can get complicated and quota code in particular needs to obtain some quota locks which leads to potential deadlock. Thus we defer dropping of inode reference to ocfs2_wq.
