Subject: [PATCH 05/10] xfs: report dir/attr block corruption errors to the health system
Date: Thu, 07 Nov 2019 23:05:58 -0800	[thread overview]
Message-ID: <157319675864.834783.9435770447884485142.stgit@magnolia> (raw)
In-Reply-To: <157319672612.834783.1318671695966912922.stgit@magnolia>

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

Whenever we encounter corrupt directory or extended attribute blocks, we
should report that to the health monitoring system for later reporting.
