From: Max Filippov <jcmvbkbc@xxxxxxxxx> 3.4.106-rc1 review patch. If anyone has any objections, please let me know. ------------------ 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.
