Several tests unmount then re-mount the scratch filesystem, to check that the content is unchanged; but unmounting a tmpfs is designed to lose its content, which causes such tests to fail unnecessarily.

# Tests the noatime, relatime, strictatime and nodiratime mount options.
|
|
# There is an extra check for Btrfs to ensure that the access time is
|
|
# never updated on read-only subvolumes. (Regression test for bug fixed
|
|
# with commit 93fd63c2f001ca6797c6b15b696a484b165b4800)
