Subject: [PATCH v2 19/22] dm: use little-endian bit operations
Date: Thu, 21 Oct 2010 23:41:14 +0900	[thread overview]
Message-ID: <1287672077-5797-20-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1287672077-5797-1-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.
