Subject: [PATCH 06/10] xfs: report symlink block corruption errors to the health system
Date: Sun, 03 Nov 2019 14:25:22 -0800
Message-ID: <157281992200.4152102.11858859069139016629.stgit@magnolia> (raw)
In-Reply-To: <157281988489.4152102.1632857939932700344.stgit@magnolia>

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

Whenever we encounter corrupt symbolic link blocks, we should report
that to the health monitoring system for later reporting.
