Subject: [PATCH v3 00/22] Introduce little endian bitops
Andrew, please consider to include this patch series into -mm.
Changelog:
* v3
- add Acked-by: lines
* v2
(cover letter for v2 was not delivered to any mailing lists I've CCed may be
due to Too many recipients to the message)
- fix argument of test_and_{set,clear}_le_bit() for s390, arm, m68k
- move ext2 bitops to fs/ext2/ext2.h, not include/linux/ext2_fs.h
- fix m68k minix bitops incorrect conversion noticed by Andreas Schwab
- rewrite minix bitops removal patch based on the suggestion by Arnd
This patch series introduces little-endian bit operations in asm/bitops.h
for all architectures and converts all ext2 non-atomic and minix bit operations
to use little-endian bit operations. it enables to remove ext2 non-atomic and
minix bit operations from asm/bitops.h. The reason they should be removed
from asm/bitops.h is as follows:
For ext2 non-atomic bit operations, they are used for little-endian byte order
bitmap access by some filesystems and modules. But using ext2_*() functions on
a module other than ext2 filesystem makes someone feel strange.
For minix bit operations, they are only used by minix filesystem and useless
by other modules. Because byte order of inode and block bitmap is defferent
on each architecture.
Akinobu Mita (22):
bitops: merge little and big endian definisions in
asm-generic/bitops/le.h
bitops: rename generic little-endian bitops functions
s390: introduce little-endian bitops
arm: introduce little-endian bitops
m68k: introduce little-endian bitops
m68knommu: introduce little-endian bitops
bitops: introduce little-endian bitops for most architectures
rds: stop including asm-generic/bitops/le.h
kvm: stop including asm-generic/bitops/le.h
asm-generic: use little-endian bitops
ext3: use little-endian bitops
ext4: use little-endian bitops
ocfs2: use little-endian bitops
nilfs2: use little-endian bitops
reiserfs: use little-endian bitops
udf: use little-endian bitops
ufs: use little-endian bitops
md: use little-endian bit operations
dm: use little-endian bit operations
bitops: remove ext2 non-atomic bitops from asm/bitops.h
m68k: remove inline asm from minix_find_first_zero_bit
bitops: remove minix bitops from asm/bitops.h
