Subject[PATCH] ocfs2: remove set but not used variable 'last_hash'
Date
Fixes gcc '-Wunused-but-set-variable' warning:

fs/ocfs2/xattr.c: In function ocfs2_xattr_bucket_find:
fs/ocfs2/xattr.c:3828:6: warning: variable last_hash set but not used [-Wunused-but-set-variable]

It's never used and can be removed.
