asm-generic: add another generic ext2 atomic bitops

2011-07-26T23:49:46Z

The majority of architectures implement ext2 atomic bitops as test_and_{set,clear}_bit() without spinlock. This adds this type of generic implementation in ext2-atomic-setbit.h and use it wherever possible.

asm-generic: use little-endian bitops

2011-03-24T02:46:15Z

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. Signed-off-by: Akinobu Mita Acked-by: Arnd Bergmann Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] bitops: generic ext2_{set,clear}_bit_atomic()

2006-03-26T16:57:11Z

This patch introduces the C-language equivalents of the functions below: int ext2_set_bit_atomic(int nr, volatile unsigned long *addr); int ext2_clear_bit_atomic(int nr, volatile unsigned long *addr); In include/asm-generic/bitops/ext2-atomic.h This code largely copied from: include/asm-sparc/bitops.h Signed-off-by: Akinobu Mita Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
