Building a kernel to test with the patch applied, will reboot into it once the call I am on has finished. Unfortunately the performance difference didn't reproduce nicely in VM...
Performance is good with the patch applied. Results are slightly better even, but I think that's likely just noise.
Could be - it's avoiding a few function calls and the flush, but would probably have to be a pretty targeted test setup to find that for storage IO. Thanks for testing!
