Subject: [PATCH 7/8] xfs: add tracepoints for high level iunlink operations
Date: Thu, 31 Jan 2019 15:18:34 -0800 [thread overview]
Message-ID: <154897671399.26065.15247361285974787568.stgit@magnolia> (raw)
In-Reply-To: <154897667054.26065.13164381203002725289.stgit@magnolia>
From: Darrick J. Wong <darrick.wong@oracle.com>
Add tracepoints so we can associate high level operations with low level
updates. No functional changes.
