support for removing files about fuse-overlayfs HOT 3 CLOSED

it looks like your kernel is returning EOPNOTSUPP when attempting to use mknod on tmpfs.

What kernel are you using?

When the mknod fails, fuse-overlayfs gives up creating the whiteout file. It should fallback to creating the .wh.$NAME version instead.

Could you try if this patch solves the issue for you?
