Subject: [PATCH v22 04/16] xfs: Return from xfs_attr_set_iter if there are no more rmtblks to process
Date: Mon, 26 Jul 2021 23:20:41 -0700	[thread overview]
Message-ID: <20210727062053.11129-5-allison.henderson@oracle.com> (raw)
In-Reply-To: <20210727062053.11129-1-allison.henderson@oracle.com>

During an attr rename operation, blocks are saved for later removal
as rmtblkno2. The rmtblkno is used in the case of needing to alloc
more blocks if not enough were available.  However, in the case
that neither rmtblkno or rmtblkno2 are set, we can return as soon
as xfs_attr_node_addname completes, rather than rolling the transaction
with an -EAGAIN return.  This extra loop does not hurt anything right
now, but it will be a problem later when we get into log items because
we end up with an empty log transaction.  So, add a simple check to
cut out the unneeded iteration.
