From: Amir Goldstein <amir73il@gmail.com>
Overlayfs should cope with online changes to underlying layer without crashing the kernel, which is what xfstest overlay/019 checks.
This test may sometimes trigger WARN_ON() in ovl_create_or_link() when linking an overlay inode that has been changed on underlying layer.
Remove those WARN_ON() to prevent the stress test from failing.
