  • Again, there's no point in passing this in every time. Make it part of
    struct sbitmap_queue and clean up the API.

  • Allocating your own per-cpu allocation hint separately makes for an
    awkward API. Instead, allocate the per-cpu hint as part of the struct
    sbitmap_queue. There's no point for a struct sbitmap_queue without the
    cache, but you can still use a bare struct sbitmap.

  • This is a generally useful data structure, so make it available to
    anyone else who might want to use it. It's also a nice cleanup
    separating the allocation logic from the rest of the tag handling logic.

    The code is behind a new Kconfig option, CONFIG_SBITMAP, which is only
    selected by CONFIG_BLOCK for now.

    This should be a complete noop functionality-wise.
