Subject: [PATCH 03/10] xfs: report block map corruption errors to the health tracking system
Date: Thu, 07 Nov 2019 23:05:45 -0800	[thread overview]
Message-ID: <157319674546.834783.2304134771257691303.stgit@magnolia> (raw)
In-Reply-To: <157319672612.834783.1318671695966912922.stgit@magnolia>

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

Whenever we encounter a corrupt block mapping, we should report that to
the health monitoring system for later reporting.
