Subject: [PATCH 10/11] xfs: trace timestamp limits
Date: Tue, 01 Sep 2020 19:57:38 -0700	[thread overview]
Message-ID: <159901545812.548109.17681490755116905605.stgit@magnolia> (raw)
In-Reply-To: <159901538766.548109.8040337941204954344.stgit@magnolia>

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

Add a couple of tracepoints so that we can check the timestamp limits
being set on inodes and quotas.
