From 6b33aff368def952be78102c0935ebd219f9a748 Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Wed, 23 Mar 2011 16:42:13 -0700 Subject: [PATCH] md: use little-endian bitops 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.
