[PATCH 022/111] xfs: report inode corruption errors to the health system

["Darrick J. Wong" <djwong@xxxxxxxxxx>]

From: Darrick J. Wong <djwong@xxxxxxxxxx>

Source kernel commit: baf44fa5c37a2357a7ae92889f74bc1824f33fd4

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