Peter Lieven 49f676a00a bitops: unroll while loop in find_next_bit() ... this patch adopts the loop unrolling idea of bitmap_is_zero() to speed up the skipping of large areas with zeros in find_next_bit(). this routine is extensively used to find dirty pages in live migration. testing only the find_next_bit performance on a zeroed bitfield the loop onrolling decreased executing time by approx. 50% on x86_64.
