Subject: [PATCH v2 10/11] ext4: remove useless brelse call in ext4_xattr_inode_update_ref()
Date: Wed, 31 Oct 2018 00:58:46 +0300	[thread overview]
Message-ID: <fb87bcc2-5e4a-34ba-a063-3f43e9de976c@virtuozzo.com> (raw)
In-Reply-To: <cover.1540935522.git.vvs@virtuozzo.com>

brelse(iloc.bh) is useless here, it is always called with iloc.bh = NULL

Fixes dec214d00e0d ("ext4: xattr inode deduplication") # 4.13
