Before 2.6.37, the md layer had a mechanism for catching I/Os with the barrier flag set, and translating the barrier into barriers for all the underlying devices. With 2.6.37, I/O barriers have become plain old flushes, and the md code was updated to reflect this. However, one piece was left out -- the md layer does not tell the block layer that it supports flushes or FUA access at all, which results in md silently dropping flush requests. Since the support already seems there, just add this one piece of bookkeeping. Signed-off-by: NDarrick J. Wong <djwong@us.ibm.com> Signed-off-by: NNeilBrown <neilb@suse.de>

Commit 4044ba58 supposedly fixed a problem where if a raid1 with just one good device gets a read-error during recovery, the recovery would abort and immediately restart in an infinite loop. However it depended on raid1_remove_disk removing the spare device from the array. But that does not happen in this case. So add a test so that in the 'recovery_disabled' case, the device will be removed. This suitable for any kernel since 2.6.29 which is when recovery_disabled was introduced.

When trying to grow an array by enlarging component devices, rdev_size_store() expects the return value of rdev_size_change() to be in sectors, but the actual value is returned in KBs. This functionality was broken by commit dd8ac336 so this patch is suitable for any kernel since 2.6.30.

Both IBX and CPT have an automatic hotplug detection mode which appears to work reliably enough that we can dispense with the manual force hotplug trigger stuff. This means that hotplug detection is as simple as reading the current hotplug register values. The first time the hotplug detection is activated, the code synchronously waits for a hotplug sequence in case the hardware hasn't bothered to do a detection cycle since being initialized.

Linus Torvalds found that it was rather trivial to trigger a system freeze: In fact, with lockdep, I don't even need to do the sysrq-d thing: it shows the bug as it happens. It's the X server taking the same lock recursively. Here's the problem: ============================================= [ INFO: possible recursive locking detected ] 2.6.37-rc2-00012-gbdbd01ac #7 --------------------------------------------- Xorg/2816 is trying to acquire lock: (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c626c>] i915_gem_fault+0x50/0x17e but task is already holding lock: (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a other info that might help us debug this: 2 locks held by Xorg/2816: #0: (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a #1: (&mm->mmap_sem){++++++}, at: [<ffffffff81022d4f>] page_fault+0x156/0x37b This recursion was introduced by rearranging the locking to avoid the double locking on the fast path (4f27b5d and fbd5a26d) and the introduction of the prefault to encourage the fast paths (b5e4f2b). In order to undo the problem, we rearrange the code to perform the access validation upfront, attempt to prefault and then fight for control of the mutex. the best case scenario where the mutex is uncontended the prefaulting is not wasted.

In that case the first process should give up trying to reserve and return -EAGAIN.
