Whiteout objects do not count as device files and do not require CAP_MKNOD since linux.git a3c751a50fe6 (2020-05-14; "vfs: allow unprivileged whiteout creation").

Thanks! I checked the referenced commit, and it seems correct.

(I'm not taking the patch yet, in case Miklos wants to comment, but
I will take it eventually.)
