[PATCH v2 0/6] bitmap: cleanup bitmap_*_region() implementation

From: Yury Norov
Date: Thu Aug 10 2023 - 20:56:32 EST


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:
- fix declaration order (patch6);
- fix kernel-doc varnings;
- don't use 'drop' wording where (patches 2-4);

Yury Norov (6):
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
