# Run the t_immutable test program for immutable/append-only files
# and directories in an overlayfs upper directory.
#
# This test is similar and was derived from generic/079, but
# the original test is _notrun with FSTYP=overlay on kernel < v5.10
# because prior to commit 61536bed2149 ("ovl: support [S|G]ETFLAGS
# and FS[S|G]ETXATTR ioctls for directories"), t_immutable -c would
# fail to prepare immutable/append-only directories on the overlay
# mount path.
