Warning when using GridEvenShare with unsigned offsets

[fkallen]

The following warning occurs when DispatchRadixSort is instantiated with an unsigned offset type.

cuda-11.0/bin/../targets/x86_64-linux/include/cub/device/dispatch/../../grid/grid_even_share.cuh: In instantiation of ‘void cub::GridEvenShare<OffsetT>::DispatchInit(OffsetT, int, int) [with OffsetT = unsigned int]’:
required from here
cuda-11.0/bin/../targets/x86_64-linux/include/cub/device/dispatch/../../grid/grid_even_share.cuh:133:37: warning: comparison of integer expressions of different signedness: ‘int’ and ‘unsigned int’ [-Wsign-compare]
  133 |         this->grid_size             = CUB_MIN(total_tiles, max_grid_size);

Minimal reproduction code:

// nvcc -std=c++14 -Xcompiler "-Wall" file.cu
// Cuda compilation tools, release 11.0, V11.0.221
// Build cuda_11.0_bu.TC445_37.28845127_0

#include <cub/cub.cuh>

int main(){
    cub::GridEvenShare<unsigned int> a;
    a.DispatchInit(1,1,1);
}

Is it safe to ignore this warning?

Heh, I literally just fixed that on my local branch for #249 yesterday :) This shouldn't be an issue after the next release.

Is it safe to ignore this warning?

Yes.
