2010-11-15net: rtnetlink.h -- only include linux/netdevice.h when used by the kernelAndy Whitcroft
The commit below added a new helper dev_ingress_queue to cleanly obtain the ingress queue pointer. This necessitated including 'linux/netdevice.h': commit 24824a09e35402b8d58dcc5be803a5ad3937bdba Author: Eric Dumazet <eric.dumazet@gmail.com> Date: Sat Oct 2 06:11:55 2010 +0000 net: dynamic ingress_queue allocation However this include triggers issues for applications in userspace which use the rtnetlink interfaces. Commonly this requires they include 'net/if.h' and 'linux/rtnetlink.h' leading to a compiler error as below: In file included from /usr/include/linux/netdevice.h:28:0, from /usr/include/linux/rtnetlink.h:9, from t.c:2: /usr/include/linux/if.h:135:8: error: redefinition of ‘struct ifmap’ /usr/include/net/if.h:112:8: note: originally defined here /usr/include/linux/if.h:169:8: error: redefinition of ‘struct ifreq’ /usr/include/net/if.h:127:8: note: originally defined here /usr/include/linux/if.h:218:8: error: redefinition of ‘struct ifconf’ /usr/include/net/if.h:177:8: note: originally defined here The new helper is only defined for the kernel and protected by __KERNEL__ therefore we can simply pull the include down into the same protected section.

2010-11-15arch/tile: fix rwlock so would-be write lockers don't block new readersChris Metcalf
This avoids a deadlock in the IGMP code where one core gets a read lock, another core starts trying to get a write lock (thus blocking new readers), and then the first core tries to recursively re-acquire the read lock. We still try to preserve some degree of balance by giving priority to additional write lockers that come along while the lock is held for write, so they can all complete quickly and return the lock to the readers.

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.

2010-11-13drm/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.
