    mm: micro-optimise slab to avoid a function call · 381760ea
    Mel Gorman authored
    Getting and putting objects in SLAB currently requires a function call but
    the bulk of the work is related to PFMEMALLOC reserves which are only
    consumed when network-backed storage is critical.  Use an inline function
    to determine if the function call is required.
