Add a sentence to the umount.8 man page to clarify the behaviour for forced dismount when used on an NFS mount point. This is a content change.

MFC: r222466

2011-06-12T02:05:59Z

Modify the umount(8) command so that it doesn't do a sync(2) syscall before unmount(2) for the "-f" case. This avoids a forced dismount from getting stuck for an NFS mountpoint in sync() when the server is not responsive. With this commit, forced dismounts should normally work for the NFS clients, but can take up to about 1minute to complete.

MFC r203490: Introduce '[ipaddr]:path' notation.

2010-02-27T18:27:32Z

Since the existing implementation searches ':' backward, a path which includes ':' could not be mounted. You can now mount such path by enclosing an IP address by '[]'. Though we should change to search ':' forward, it will break 'ipv6addr:path' which is currently working. So, it still searches ':' backward, at least for now.
