    Subject[RFC PATCH v1 05/37] perf util/mmap: add missing bitops.h header
    Date
    MMAP_CPU_MASK_BYTES uses the BITS_TO_LONGS macro, which is defined in
    linux/bitops.h.
    However, this header is not included directly, but gets imported
    indirectly in files using the macro.
    This patch adds the missing include.
