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.
It's not in the final state (if nothing else, it needs to be rebased on top of xarray stuff, and there will be followup cleanups as well), but I'd appreciate testing and profiling data... It does survive xfstests + LTP syscall tests, but that's about it.
