2010-11-15GFS2: Fix inode deallocation raceSteven Whitehouse
This area of the code has always been a bit delicate due to the subtleties of lock ordering. The problem is that for "normal" alloc/dealloc, we always grab the inode locks first and the rgrp lock later. In order to ensure no races in looking up the unlinked, but still allocated inodes, we need to hold the rgrp lock when we do the lookup, which means that we can't take the inode glock. The solution is to borrow the technique already used by NFS to solve what is essentially the same problem (given an inode number, look up the inode carefully, checking that it really is in the expected state). We cannot do that directly from the allocation code (lock ordering again) so we give the job to the pre-existing delete workqueue and carry on with the allocation as normal. If we find there is no space, we do a journal flush (required anyway if space from a deallocation is to be released) which should block against the pending deallocations, so we should always get the space back.

2010-11-15Input: sysrq - pass along lone Alt + SysRqDmitry Torokhov
When user presses and releases Alt + SysRq without pressing any of the hot keys re-inject the combination and pass it on to userspace instead of suppressing it - maybe he or she wanted to take print screen instead of invoking SysRq handler. Also pass along release events for keys that have been pressed before SysRq mode has been invoked so that keys do not appear to be "stuck".

2010-11-13drm/i915: Retire any pending operations on the old scanout when switchingChris Wilson
An old and oft reported bug, is that of the GPU hanging on a MI_WAIT_FOR_EVENT following a mode switch. The cause is that the GPU is waiting on a scanline counter on an inactive pipe, and so waits for a very long time until eventually the user reboots his machine. We can prevent this either by moving the WAIT into the kernel and thereby incurring considerable cost on every swapbuffers, or by waiting for the GPU to retire the last batch that accesses the framebuffer before installing a new one. As mode switches are much rarer than swap buffers, this looks like an easy choice.

This patch increases the length of the buffer accordingly. http://marc.info/?l=linux-netdev&m=128872251418192&w=2 Reported-by: Dan Rosenberg <drosenberg@vsecurity.com> Signed-off-by: Oliver Hartkopp <socketcan@hartkopp.net> CC: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: David S.

2010-11-12gianfar: Do not call device_set_wakeup_enable() under a spinlockRafael J. Wysocki
The gianfar driver calls device_set_wakeup_enable() under a spinlock, which causes a problem to happen after the recent core power management changes, because this function can sleep now. Fix this by moving the device_set_wakeup_enable() call out of the spinlock-protected area. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: David S. Miller <davem@davemloft.net>
