4 # Test copy-up of lowerdir with opaque xattr set.
6 # When copying up a directory with opaque xattr set, the xattr was copied up as
7 # well, after a remount the opaque flag is honored so the copied-up directory
8 # is treated as opaque, which causes files created in the lowerdir to be hidden
9 # when using multiple lower directories.
11 # This is fixed by "ovl: don't copy up opaqueness".
