    Subject[patch 14/30] NET: __alloc_pages() failures reported due to fragmentation
    -stable review patch.  If anyone has any objections, please let us know.

    From: David Miller <>

    We have seen a couple of __alloc_pages() failures due to
    fragmentation, there is plenty of free memory but no large order pages
    available. I think the problem is in sock_alloc_send_pskb(), the
    gfp_mask includes __GFP_REPEAT but its never used/passed to the page
    allocator. Shouldnt the gfp_mask be passed to alloc_skb() ?
