This series unifies declarations of bitmap-related functions and aligns return types with values that actually returned. Also, it moves one-liner wrappers around cpumask functions into headers, so that compiler has a chance to optimize better. With this series, GCC 11.2 for ARM64 with kernel v5.19-rc4: add/remove: 15/7 grow/shrink: 461/164 up/down: 14844/-4580 (10264) This +10K didn't surprize me because modern compilers are more agressive in inlining, loop unrolling, and other techniques that increase size of the image. Yury Norov (8): arm: align find_bit defs with generic kernel lib/bitmap: change return values to bool where appropriate lib/bitmap: change type of bitmap_weight to unsigned int cpumask: change return types to bool where appropriate lib/cpumask: change return types to unsigned lib/cpumask: move one-line wrappers around find_bit to the header mm: split include/linux/gfp.h lib/cpumask: move some one-line wrappers to header file Documentation/core-api/mm-api.rst | 8 +- MAINTAINERS | 1 + arch/arm/include/asm/bitops.h | 20 +- include/linux/bitmap.h | 10 +- include/linux/cpumask.h | 125 +++++++++-- include/linux/gfp.h | 334 +---------------------------- include/linux/gfp_flags.h | 338 ++++++++++++++++++++++++++++++ lib/bitmap.c | 9 +- lib/cpumask.c | 97 +-------- tools/include/linux/bitmap.h | 12 +- tools/lib/bitmap.c | 6 +- 11 files changed, 483 insertions(+), 477 deletions(-) create mode 100644 include/linux/gfp_flags.h -- 2.34.1
