[PATCH v2] mm,kmemleak-test: add the dependency on CONFIG_SAMPLES

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Xiang Chen <chenxiang66@xxxxxxxxxxxxx>

As kmemleak-test.c is moved to samples dir, it is not compiled if just
setting CONFIG_DEBUG_KMEMLEAK_TEST as module and enabling
CONFIG_DEBUG_KMEMLEAK.
So move the DEBUG_KMEMLEAK_TEST option to samples dir as well and rename 
it to SAMPLE_KMEMLEAK_TEST. And also replace DEBUG_KMEMLEAK_TEST with
SAMPLE_KMEMLEAK_TEST in some other places.

Fixes: 1abbef4f5172 ("mm,kmemleak-test.c: move kmemleak-test.c to samples dir")
