    One concern I had regarding relayfs, which was raised previously, was
    regarding its use of vmap,
    http://marc.theaimsgroup.com/?l=linux-kernel&m=110755199913216&w=2 On x86,
    the vmap space is at a premium, and this space is reserved over the entire
    lifetime of a 'channel'. Is the use of vmap really critical for
    performance?

    thanks,
