Subject: [PATCH 16/26] xfs: stop using q_core timers in the quota code
Date: Tue, 14 Jul 2020 18:52:20 -0700 [thread overview]
Message-ID: <159477794006.3263162.13868334199685757765.stgit@magnolia> (raw)
In-Reply-To: <159477783164.3263162.2564345443708779029.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.
