Subject: [PATCH 02/13] libxfs: rename XFS_CMP_CASE to XFS_CMP_MATCH
Date: Thu, 11 Sep 2014 15:52:38 -0500	[thread overview]
Message-ID: <20140911205238.GK13262@sgi.com> (raw)
In-Reply-To: <20140911203735.GA19952@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.

Signed-off-by: Olaf Weber <olaf@sgi.com>
