Subject: [PATCH 7/9] xfs: report inode corruption errors to the health system
Date: Thu, 14 Nov 2019 10:19:59 -0800	[thread overview]
Message-ID: <157375559910.3692735.16877132028535941668.stgit@magnolia> (raw)
In-Reply-To: <157375555426.3692735.1357467392517392169.stgit@magnolia>

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

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