Subject: [PATCH 08/25] libxfs: make libxfs_readbuf_verify return an error code
Date: Mon, 24 Feb 2020 16:12:19 -0800 [thread overview]
Message-ID: <158258953956.451378.12584291966139198190.stgit@magnolia> (raw)
In-Reply-To: <158258948821.451378.9298492251721116455.stgit@magnolia>
From: Darrick J. Wong <darrick.wong@oracle.com>
Return the bp->b_error from libxfs_readbuf_verify instead of making
callers check it.
Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com>
