Change test to output golden silence on success. We are going to run the same check several times, so instead of cloning the test output, cloning the silence will be more conveniet. Generalize cleanup of temp files for the same reason. Signed-off-by: Amir Goldstein <amir73il@gmail.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>

# Test unstable inode number
|
|
#
|
|
# This simple test demonstrates a known issue with overlayfs:
|
|
# - stat file A shows inode number X
|
|
# - modify A to trigger copy up
|
|
# - stat file A shows inode number Y != X
|
|
#
|
|
# Also test if d_ino of readdir entries changes after copy up.
