    Subject[PATCH 4.19 52/85] ocfs2: remove set but not used variable last_hash
    Date
    [ Upstream commit 7bc36e3ce91471b6377c8eadc0a2f220a2280083 ]

    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.
