Date: Thu, 20 Jul 2023 17:45:49 +0800 [thread overview]
Message-ID: <20230720094555.1397621-1-chengming.zhou@linux.dev> (raw)
From: Chengming Zhou <zhouchengming@bytedance.com>
Hello,
This series aim to fix and simplify the offset hint wrap logic, also
include some minor optimizations.
patch 01,02 fix offset hint wrap logic in strict round-robin mode.
patch 03,04 simplify the sbitmap_find_bit() code by removing wrap logic.
patch 05,06 are two minor optimizations.
Thanks!
Chengming Zhou (6):
sbitmap: fix hint wrap in the failure case
sbitmap: fix round-robin non-wrap find with hint > 0
sbitmap: don't loop twice in find_next_zero_bit()
sbitmap: remove offset wrap logic when finding bit in word
sbitmap: wake_index doesn't need to be atomic_t
sbitmap: check ws_active before check waitqueues
