Subject: [PATCH 02/15] xfs: detach inode dquots at the end of inactivation
Date: Wed, 02 Jun 2021 15:25:08 -0700	[thread overview]
Message-ID: <162267270808.2375284.11171512285980946391.stgit@locust> (raw)
In-Reply-To: <162267269663.2375284.15885514656776142361.stgit@locust>

From: Darrick J. Wong <djwong@kernel.org>

Once we're done with inactivating an inode, we're finished updating
metadata for that inode.  This means that we can detach the dquots at
the end and not have to wait for reclaim to do it for us.
