[PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_sem

Browse source 
This patch converts the inode semaphore to a mutex. I have tested it on
XFS and compiled as much as one can consider on an ia64. Anyway your
luck with it might be different.

Modified-by: Ingo Molnar <mingo@elte.hu>

(finished the conversion)
