Subject: fuse: fix bug in control filesystem mount
From: Miklos Szeredi <miklos@xxxxxxxxxx>
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.
