bitops: remove ext2 non-atomic bitops from asm/bitops.h
Akinobu Mita [Wed, 23 Mar 2011 23:42:14 +0000 (16:42 -0700)]
As the result of conversions, there are no users of ext2 non-atomic bit
operations except for ext2 filesystem itself.  Now we can put them into
architecture independent code in ext2 filesystem, and remove from
asm/bitops.h for all architectures.
