Subject: [PATCH 08/10] xfs: report quota block corruption errors to the health system
Date: Tue, 31 Dec 2019 17:05:34 -0800	[thread overview]
Message-ID: <157784073466.1360095.15118948899431651589.stgit@magnolia> (raw)
In-Reply-To: <157784067947.1360095.12276226432994685051.stgit@magnolia>

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

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