Subject: [PATCH 22/35] libxfs: rename XFS_CMP_CASE to XFS_CMP_MATCH
Date: Fri, 3 Oct 2014 17:09:59 -0500	[thread overview]
Message-ID: <20141003220959.GV1865@sgi.com> (raw)
In-Reply-To: <20141003214758.GY1865@sgi.com>

From: Olaf Weber <olaf@sgi.com>

Rename XFS_CMP_CASE to XFS_CMP_MATCH. With unicode filenames and
normalization, different strings will match on other criteria than
case insensitivity.
