Subject: [RFC v5 PATCH 2/9] xfs: introduce ->tr_relog transaction
Date: Thu, 27 Feb 2020 08:43:14 -0500 [thread overview]
Message-ID: <20200227134321.7238-3-bfoster@redhat.com> (raw)
In-Reply-To: <20200227134321.7238-1-bfoster@redhat.com>
Create a transaction reservation specifically for relog
transactions. For now it only supports the quotaoff intent, so use
the associated reservation.
Signed-off-by: Brian Foster <bfoster@redhat.com>
