# 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.
