For some reason this patch appears to make lib/locking-selftest.c really unhappy.
I get endless streams of:
../lib/locking-selftest.c: In function ‘ww_test_fail_acquire’: ../lib/locking-selftest.c:1141:6: error: void value not ignored as it ought to be ret = WWL(&o, &t); ^
Apparently GCC gets confused about __much_check on inline functions or something, or I got the patch wrong.
Weird, I'm not getting that, and it makes no sense either from a quick glimpse of the code. Is there anything beside CONFIG_DEBUG_LOCKING_API_SELFTESTS I would have to enable to trigger this?
Not entirely sure, I'm building an allmodconfig.
