could you please also fix this checkpatch error (preferably as a separate patch):
mqns.h:37: ERROR: "foo* bar" should be "foo *bar"
mqns.h:96: WARNING: __func__ should be used instead of gcc specific __FUNCTION__
Checkpatch also reports wrong comment style, but I'd ignore it (complains for
*.h, it's ok for *.c):
mqns.h:1: WARNING: Improper SPDX comment style for 'mqns.h', please use '/*' instead
@Richie: not sure I might have asked before: it'd be great to have make target
also for header files, so that they are checked with make check. Now we have to
run checkpatch manually to check them.
Kind regards,
Petr

checkpatch.pl doesn't load included headers so they must be passed to
it specifically. This change automatically includes headers from the
current directory. Manual intervention is still required if a test
author changes a header located elsewhere. However you can now write
'make check-header.h', once in the correct directory.
Note that our Sparse based tool (amongst others) loads headers and
checks at least some of the content.

Thanks a lot for implementing this.
LGTM, just a small nit: target for headers contain .h extension.
Shouldn't we add .c for C sources for consistency?
It'đ strange, that make check in testcases/misc/math/float/ does not include
tfloat.h, but make check-tfloat.h prints errors. But make check in lib/ works as
expected (adds also *.h).

The Sparse based tool does include headers though. So really we are
checking the target which includes more than just a single c file.

ltp_clone_quick is still part of the old API and only uses clone2. I
think it should be replaced with tst_clone. This may require extending
tst_clone. In fact we probably need a test variant to switch between the
clone2 and clone3 syscalls when using tst_clone.
I'll leave it to you whether you want to try that and rebase this patch
set on it.

I see ltp_clone_quick as wrapper of ltp_clone, since it's using
ltp_alloc_stack without calling it explicitly all the times before
ltp_clone.

ltp_clone is also part of the old API. At some point we should remove that.

I'm marking this as changes requested. tst_clone should be made to
support this scenario.

Hi
Are we sure that we don't need this modification before adding
tst_clone? We can add the patch and then starting to think how to
replace tst_clone_quick with tst_clone in all tests.

It would be easier to just submit one test for review and iterate on
it. This follows the principal of breaking work down into the smallest
chunk practically possible.
Sometimes submitting a large patchset is unavoidable, but this is not
the case here.
I'm setting all of these to "changes requested".

You're not the first person to use this argument. So it's actually
important for precisely the reason you don't want to do it. The next
person wont' want to do it either and we'll sleep walk into never
replacing it.
Meanwhile there are solid reasons why clone3 exists and why we should
test it. That's possibly more important than the API conversion.
BTW I could take over one of these patches and do the work on
tst_clone? I'm pretty familiar with it.
