I updated this to mention that it's for madvise(MADV_HWPOISON):
: Currently the return value of memory_failure() is not passed to userspace : when madvise(MADV_HWPOISON) is used. This is inconvenient for test : programs that want to know the result of error handling. So let's return : it to the caller as we already do in the MADV_SOFT_OFFLINE case.
btw, MADV_SOFT_OFFLINE and MADV_HWPOISON are not documented in that comment block over sys_madvise(). Fixy please? You might want to check that no other MADV_foo values have been omitted.
