    sbitmap: add sbitmap_get_shallow() operation · c05e6673
    Omar Sandoval authored
    This operation supports the use case of limiting the number of bits that
    can be allocated for a given operation. Rather than setting aside some
    bits at the end of the bitmap, we can set aside bits in each word of the
    bitmap. This means we can keep the allocation hints spread out and
    support sbitmap_resize() nicely at the cost of lower granularity for the
    allowed depth.
