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.
I'm actually a bit confused about why umount(8) calls sync(2) at all: surely it's the responsibility of the file system, rather than the userland tool, to ensure consistency subject to file system configuration and unmount-time flags?
