Linus, please apply before 2.6.20.  Thanks.

The BUG in fuse_ctl_add_dentry() could be triggered if the control
filesystem was unmounted and mounted again while one or more fuse
filesystems were present.

The fix is to reset the dentry counter in fuse_ctl_kill_sb().

Bug reported by Florent Mertens.
