    If sending routines can work with constant ammount of memory, why use
    kmalloc at all? Anyway I thought we were talking receiving side
    earlier in the thread.

    Ouch and wait a moment. You claim that GFP_KERNEL allocations can't
    block/sleep? Of course they can, that's why they are GFP_KERNEL and
    not GFP_ATOMIC.
    Thanks, Sharp!
