[PATCH v2 0/2] bitops: Optimize fns() for improved performance

[Kuan-Wei Chiu <visitorckw@gmail.com>]

Hello,

This patch series optimizes the fns() function by avoiding repeated
calls to __ffs(). Additionally, tests for fns() have been added in
lib/find_bit_benchmark.c.

Changes in v2:
- Add benchmark test for fns() in lib/find_bit_benchmark.c.
- Change the loop in fns() by counting down from n to 0.
- Add find_bit benchmark result for find_nth_bit in commit message.
