Specifically, it ensures that current_chrooted() check is applied unconditionally when setting the root to failfs (FD_FAILFS_ROOT), preventing even privileged callers (CAP_SYS_CHROOT) from escaping an existing chroot jail via failfs. This touches core VFS syscall handling and is directly reachable from userspace.)
