Subject: [PATCH 03/11] xfs_scrub: better reporting of metadata media errors
Date: Wed, 25 Sep 2019 14:36:26 -0700	[thread overview]
Message-ID: <156944738604.300131.8278382614496808681.stgit@magnolia> (raw)
In-Reply-To: <156944736739.300131.5717633994765951730.stgit@magnolia>

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

When we report bad metadata, we inexplicably report the physical address
in units of sectors, whereas for file data we report file offsets in
units of bytes.  Fix the metadata reporting units to match the file data
units (i.e. bytes) and skip the printf for all other cases.
