    [PATCH] USB ohci-hcd, don't force SLAB_ATOMIC allocations · fb4b62ad
    David Brownell authored
    This is a minor cleanup to let per-request memory allocations block,
    when the caller allows (it provided the bitmask).  The driver used
    to work that way until something like 2.4.3; an update (a few months
    back) to how the "dma_addr_t" hashes to a "struct ohci_td *" lets us
    simplify things again.  Another benfit:  it blocks irqs for less time
    on the submit path.  (The ehci driver already acts this way.)
