Hi, Should we pick this patch for 5.13?Looks ok to meLooks sane. BTW, Pavel, could you go over #untested.iov_iter and give it some beating? Ideally - with per-commit profiling to see what speedups/slowdowns do they come with...I've heard Jens already tested it out. Jens, is that right? Can you share? especially since you have much more fitting hardware.
FWIW, the current branch is #untested.iov_iter-3 and the code generated by it at least _looks_ better than with mainline; how much of an improvement does it make would have to be found by profiling...
