The patch titled
reiserfs: use little-endian bitops
has been removed from the -mm tree. Its filename was
reiserfs-use-little-endian-bitops.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: reiserfs: use little-endian bitops
From: Akinobu Mita <akinobu.mita@xxxxxxxxx>
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.
