Subject: [PATCH 18/22] md: use little endian bit operations
Date: Fri, 15 Oct 2010 18:46:17 +0900 [thread overview]
Message-ID: <1287135981-17604-19-git-send-email-akinobu.mita@gmail.com> (raw)
In-Reply-To: <1287135981-17604-1-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.
