Hi John,

commit 30fb9454ab23 ("selftests/vm: hmm-tests: remove the libhugetlbfs
dependency") created the new check_config.sh file without the execute
bits set. This is a problem because the Makefile runs it with "./", so
now "make" is failing in that directory.

The posted patch [1] does seem to have it as an executable file, so I'm
not sure how this happened. But in any case, make check_config.sh
executable again, so that "make" in selftests/vm works once again.

The correct fix is to make sure that the Makefile runs it explicitly
with a shell because is such a patch is applied with patch(1), the
execute bit will not be preserved.

See e.g. in the top level Makefile:

	$(CONFIG_SHELL) $(srctree)/scripts/gen_autoksyms.sh $@


OK...we should also fix it anyway, seeing as how the run_vmtest.sh also needs
the execute bit re-set, yes?

So I guess I should send a patch that does:

* chmod +x on both run_vmtest.sh and check_config.sh, plus

* invoke check_config.sh via $(CONFIG_SHELL) from the Makefile.

Does that sound about right?

thanks,
