Subject: [PATCH v2] xfs: Remove redundant assignment of mp
Date: Wed,  5 Jan 2022 23:15:36 +0800	[thread overview]
Message-ID: <20220105151536.39062-1-jiapeng.chong@linux.alibaba.com> (raw)

mp is being initialized to log->l_mp but this is never read
as record is overwritten later on. Remove the redundant
assignment.

Cleans up the following clang-analyzer warning:

fs/xfs/xfs_log_recover.c:3543:20: warning: Value stored to 'mp' during
its initialization is never read [clang-analyzer-deadcode.DeadStores].
