If anyone has any objections, please let me know. ------------------ From: Max Filippov commit 2651cc6974d47fc43bef1cd8cd26966e4f5ba306 upstream. Userspace actually passes single parameter (path name) to the umount syscall, so new umount just fails. Fix it by requesting old umount syscall implementation and re-wiring umount to it.
