From 6711069dd72fcbafe010fb16be504364e5ced190 Mon Sep 17 00:00:00 2001 From: Ryota Sakamoto Date: Fri, 23 Jan 2026 00:40:41 +0900 Subject: lib/tests: extend KUnit test for bitops with more cases Extend a KUnit test suite for the bitops API to cover more APIs from include/asm-generic/bitops/instrumented-atomic.h. - change_bit() - test_and_set_bit() - test_and_clear_bit() - test_and_change_bit() Verified on x86_64, i386, and arm64 architectures.
