Richard Weinberger 32fe905c17 ubifs: Fix O_TMPFILE corner case in ubifs_link() ... It is perfectly fine to link a tmpfile back using linkat(). Since tmpfiles are created with a link count of 0 they appear on the orphan list, upon re-linking the inode has to be removed from the orphan list again. Ralph faced a filesystem corruption in combination with overlayfs due to this bug.
