[PATCH 0/3] selftests/landlock: UX improvements

[Tingmao Wang]

Hi,

A while ago I tried running the landlock selftests and it took me a while
to get it completely working.  One of the main thing which confused me a
bit was the fact that I was missing the right permissions on the test
directory, and this matters even though I ran the test with root.

The other slightly annoying thing was that the mkdir would fail with
EEXIST if a previous run fails to setup.

This patch series tries to improve the experience should someone else runs
into the same issues.

Tingmao Wang (3):
  selftests/landlock: Clean up tmp directory even when mount fails
  selftests/landlock: Print a warning about directory permissions
  selftests/landlock: Clean up TMP_DIR and retry if dir already exists
