Subject[PATCH v2 00/10] lib: cleanup bitmap-related headers
Date
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 surprise me because modern compilers are more aggressive
in inlining, loop unrolling, and other techniques that increase size of
the image.

v1: https://lore.kernel.org/linux-mm/YsAzU3g2QpgmIGre@smile.fi.intel.com/T/
v2: - Align whitespaces in headers;
- Make bitmap_weight() unsigned long consistently;
- Pick 2 patches from Ingo's sched/headers series [1] that split
linux/gfp.h, and drop my similar patch for it.

[1] https://git.kernel.org/pub/scm/linux/kernel/git/mingo/tip.git/log/?h=sched/headers

Ingo Molnar (2):
headers/deps: mm: Optimize <linux/gfp.h> header dependencies
headers/deps: mm: Split <linux/gfp_types.h> out of <linux/gfp.h>

Yury Norov (8):
arm: align find_bit declarations with generic kernel
lib/bitmap: change return types to bool where appropriate
lib/bitmap: change type of bitmap_weight to unsigned long
cpumask: change return types to bool where appropriate
lib/cpumask: change return types to unsigned where appropriate
lib/cpumask: move trivial wrappers around find_bit to the header
headers/deps: mm: align MANITAINERS and Docs with new gfp.h structure
lib/cpumask: move some one-line wrappers to header file
