Series bitmap: optimize small_const path for |

Message

Yury Norov Oct. 27, 2022, 4:38 a.m. UTC 
  Make all inline bitmap functions __always_inline to ensure that
small_const optimization is always possible, and improve on it for
find_next_bit() and friends.

Yury Norov (3):
  bitmap: switch from inline to __always_inline
  bitmap: improve small_const case for find_next() functions
  bitmap: add tests for find_next_bit()
