This patchset optimizes several places which take the per inode spin lock. They have not been fully tested yet, thus they are marked as RFC.
I do limited tests after all patches applied: use two 'find' to traverse the filesystems and touch all files in parallel. This runs for several days in a virtual machine, no suspicious log appears.
Guo Chao (4): fs/inode.c: do not take i_lock on newly allocated inode fs/inode.c: do not take i_lock in __(insert|remove)_inode_hash fs/inode.c: do not take i_lock when identify an inode fs/inode.c: always take i_lock before calling filesystem's test() method
