Subject: [PATCH v3 1/2] selftests/vm: fix an improper dependency upon executable script permissions
Date: Fri, 2 Oct 2020 17:21:41 -0700	[thread overview]
Message-ID: <20201003002142.32671-2-jhubbard@nvidia.com> (raw)
In-Reply-To: <20201003002142.32671-1-jhubbard@nvidia.com>

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

Scripts are not supposed to depend on the executable bit being set,
because patch(1) doesn't set it, and using patch to install a kernel is
supported. Therefore, this fix involves two parts:

1) Invoke the new script via /bin/sh, to fix the problem, and

2) As an nice touch, make check_config.sh executable as well.

Fixes: commit 30fb9454ab23 ("selftests/vm: hmm-tests: remove the libhugetlbfs dependency")
