>Description:
umount /proc or umount /proc/ say "umount: /proc: not currently mounted" and fail to unmount the proc-filesystem if it was mounted with a trailing slash (only possible by calling mount_procfs yourself, mount -t procfs strips the slash). A program doing unmount("/proc/", 0) or unmount("/proc", 0) using unmount(2) works fine, so the kernel seems perfectly capable of handling the slash.

>How-To-Repeat:
mount_procfs /proc/ /proc/
umount /proc
