    This symbol name has nothing to do with its purpose. The entire area of
    code you are modifying could be described as having something to do with

    GFP_EMERGENCY or GFP_USE_RESERVES or somesuch would be a far better
    symbol name.

    I recognize that is matches with GFP_NOMEMALLOC, but that doesn't change
    the situation anyway. In fact, a cleanup patch to rename GFP_NOMEMALLOC
    would be nice.
