    SubjectRe: [PATCH 13/17] netvm: Set PF_MEMALLOC as appropriate during SKB processing
    From: Mel Gorman <>

    > needed to proceed, ensure processing of pfmemalloc SKBs happens
    > under PF_MEMALLOC. This is limited to a subset of protocols that
    > are expected to be used for writing to swap. Taps are not allowed to
    > use PF_MEMALLOC as these are expected to communicate with userspace
    > processes which could be paged out.
