Subject: [PATCH v5 24/27] dm: use little-endian bitops
Date: Sat, 22 Jan 2011 22:13:56 +0900	[thread overview]
Message-ID: <1295702039-23186-25-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1295702039-23186-1-git-send-email-akinobu.mita@gmail.com>

As a preparation for removing ext2 non-atomic bit operations from
asm/bitops.h.  This converts ext2 non-atomic bit operations to
little-endian bit operations.
