Previously _scratch_mount didn't check the mount status and most tests continue to run even if the mount failed (unless test checks for the mount status explicitly). This would result in running tests on the underlying filesystem (usually rootfs) and implicit test failures, and such failures can be annoying and are usually hard to debug. Now _fail test by default if _scratch_mount failed and introduce _try_scratch_mount for tests that need to check mount results themselves.

# Check get/set ACLs to/from disk with a user namespace. A new file
|
|
# will be created and ACLs set on it from both inside a userns and
|
|
# from init_user_ns. We check that the ACL is is correct from both
|
|
# inside the userns and also from init_user_ns. We will then unmount
|
|
# and remount the file system and check the ACL from both inside the
|
|
# userns and from init_user_ns to show that the correct uid/gid in
|
|
# the ACL was flushed and brought back from disk.
