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

Posted by Yury Norov 2 years, 6 months ago

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.

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()
  bitmap: move functions
