Greeting,
FYI, we noticed a 20.7% improvement of reaim.jobs_per_min due to commit:
commit: 7b04b5c2d33be36638b78d5584a2b3b1ff1fd3d5 ("btrfs: switch to iomap_dio_rw()
for dio")
https://github.com/kdave/btrfs-devel.git next/goldwyn/dio-iomap-20200707
in testcase: reaim
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 256G memory
with following parameters:
runtime: 300s
nr_task: 100
