Subject: [PATCH] ocfs2: remove set but not used variable 'last_hash'
Date: Tue, 16 Jul 2019 21:21:10 +0800
Message-ID: <20190716132110.34836-1-yuehaibing@huawei.com> (raw)

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.
