Merge branch 'locking-rwsem-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull support for killable rwsems from Ingo Molnar:
"This, by Michal Hocko, implements down_write_killable().
The main usecase will be to update mm_sem usage sites to use this new
API, to allow the mm-reaper introduced in commit aac453635549 ("mm,
oom: introduce oom reaper") to tear down oom victim address spaces
asynchronously with minimum latencies and without deadlock worries"
[ The vfs will want it too as the inode lock is changed from a mutex to
a rwsem due to the parallel lookup and readdir updates ]
