[PATCH 4/9] lkdtm/bugs: XFAIL UNALIGNED_LOAD_STORE_WRITE

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

 



When built under CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS, this test is
expected to fail (i.e. not trip an exception).

Fixes: 46d1a0f03d66 ("selftests/lkdtm: Add tests for LKDTM targets")
