Subject: [PATCH 0/3] bitmap: optimize small_const path for
Date: Wed, 26 Oct 2022 21:38:07 -0700 [thread overview]
Message-ID: <20221027043810.350460-1-yury.norov@gmail.com> (raw)
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()
