Subject: [patch] xfs: don't allow negative error tags
Date: Fri, 24 Jun 2016 15:22:34 +0300	[thread overview]
Message-ID: <20160624122234.GA23169@mwanda> (raw)

Errors go from zero which means no error to XFS_ERRTAG_MAX (22).  My
static checker complains that xfs_errortag_add() puts an upper bound on
this but not a lower bound.  Let's fix it by making it unsigned.
