Subject: [PATCH v3 0/8] bitmap: cleanup bitmap_*_region() implementation
bitmap_{allocate,find_free,release}_region() functions are implemented
on top of _reg_op() machinery. It duplicates existing generic functionality
with no benefits. In fact, generic alternatives may work even better
because they optimized for small_const_nbits() case and overall very well
optimized for performance and code generation.
This series drops _reg_op() entirely.
v2: https://lore.kernel.org/lkml/20230811005732.107718-2-yury.norov@gmail.com/T/
v3:
- add test for the functions;
- fix bitmap_alloc_region();
- fix comments and wrappers style.
Yury Norov (8):
bitmap: align __reg_op() wrappers with modern coding style
bitmap: add test for bitmap_*_region() functions
bitmap: fix opencoded bitmap_allocate_region()
bitmap: replace _reg_op(REG_OP_ALLOC) with bitmap_set()
bitmap: replace _reg_op(REG_OP_RELEASE) with bitmap_clear()
bitmap: replace _reg_op(REG_OP_ISFREE) with find_next_bit()
bitmap: drop _reg_op() function
bitmap: move bitmap_*_region functions to bitmap.h
