Subject: [PATCH v11 13/25] xfs: Remove unneeded xfs_trans_roll_inode calls
Date: Mon, 20 Jul 2020 17:15:54 -0700	[thread overview]
Message-ID: <20200721001606.10781-14-allison.henderson@oracle.com> (raw)
In-Reply-To: <20200721001606.10781-1-allison.henderson@oracle.com>

Some calls to xfs_trans_roll_inode and xfs_defer_finish routines are not
needed. If they are the last operations executed in these functions, and
no further changes are made, then higher level routines will roll or
commit the transactions.
