Subject: [PATCH 05/18] xfs: stop using q_core.d_id in the quota code
Date: Tue, 30 Jun 2020 08:42:23 -0700 [thread overview]
Message-ID: <159353174298.2864738.13894827380600479929.stgit@magnolia> (raw)
In-Reply-To: <159353170983.2864738.16885438169173786208.stgit@magnolia>
From: Darrick J. Wong <darrick.wong@oracle.com>
Add a dquot id field to the incore dquot, and use that instead of the
one in qcore. This eliminates a bunch of endian conversions and will
eventually allow us to remove qcore entirely.
We also rearrange the start of xfs_dquot to remove padding holes, saving
8 bytes.
