[PATCH] fuse: fix bug in control filesystem mount
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.
