Simply use the first argument to specify the subset of selftests.
Use comma notation to separate multiple tests.
(e.g. ./run_kselftest.sh size,timers,...)
Each selftest be defined as function that we can run one of selftests.
The function name has underline as prefix to avoid confilct with
built-i
Looks good.

the only other weird case that comes to mind; what happens if there's a line
dirty in the caches,
but the memory is now mapped uncached. (Which could happen if kexec does muck
with MTRRs, CR0 or other similar
things in weird ways)... not sure what happens in

By all means, try it.

Applied to 4.16/scsi-queue.

wbinvd is thankfully not common, but also not rare (MTRR setup and a bunch of
other cases)
and in some other operating systems it happens even more than on Linux.. it's
generally not totally broken like this.

BLK_STS_RESOURCE can be returned from driver when any resource
is running out of. And the resource may not be related with tags,
such as kmalloc(GFP_ATOMIC), when queue is idle under this kind of
BLK_STS_RESOURCE, restart can't work any more, then IO hang may
be caused.
Most of drivers may call km
