As preparation step for configuring test/scratch base fs for overlay tests: - Rename OVERLAY_LOWER/UPPER/WORK_DIR => OVL_LOWER/UPPER/WORK because we want to use OVL_ prefix for all base fs vars - Prepend "ovl-" prefix to lower/upper/work path values to isolate the overlay test dirs when running on a base fs that is also used to run non overlay tests - Make those vars values non-configurable, because lower/upper/work directory names are an internal test detail which should not concern the user and because we wish to simplify and document the overlay tests setup - Add helper _filter_ovl_dirs and use it to filter output of test overlay/023 which matches the constant string "work" Signed-off-by: Amir Goldstein <amir73il@gmail.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>

# FS QA Test 003
|
|
#
|
|
# Test overlayfs basic whiteout.
|
|
#
|
|
# Overlayfs whiteout can be visible if underlying upper fs does not
|
|
# support d_type. Kernel commit
|
|
# 45aebea (ovl: Ensure upper filesystem supports d_type)
|
|
# prevents mounting overlayfs like this since v4.6-rc1.
|
|
# No harm to keep this test as a sanity check.
