This function, based on murmurhash3, has much better distribution than the original. Using the current default of 2048 buckets, there are many fewer collisions: Before: 101421 entries and 2048/2048 buckets used, longest chain length 374 After: 101421 entries and 2048/2048 buckets used, longest chain length 81 The difference becomes much more significant when buckets are increased. A naive attempt to expand the current function to larger outputs doesn't yield any significant improvement; so this function is a prerequisite for increasing the bucket size. sds: Adapted from the original patches for libsepol to the kernel.
