Provided by: freebsd-manpages_7.0-2_all vfs_mountedon - check if
the vnode belongs to a mounted file system vfs_mountedon(struct
vnode *vp); vfs_mountedon() inspects the mount structure in vp
to determine if it points to a valid mount point. If the mount
is valid, the vnode is considered to be busy. A common use of
vfs_mountedon() is to call it on device vnodes to determine if
they are already associated with a file system. This is done to
prevent multiple mounts on the same device. EBUSY is returned if
the vnode has a valid mount point; otherwise, 0 is
