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
