Subject: [PATCH 10/18] xfs: stop using q_core timers in the quota code
Date: Tue, 30 Jun 2020 08:42:54 -0700	[thread overview]
Message-ID: <159353177481.2864738.2222411495060044495.stgit@magnolia> (raw)
In-Reply-To: <159353170983.2864738.16885438169173786208.stgit@magnolia>

From: Darrick J. Wong <darrick.wong@oracle.com>

Add timers fields to the incore dquot, and use that instead of the ones
in qcore.  This eliminates a bunch of endian conversions and will
eventually allow us to remove qcore entirely.
