I have tested with fio:
[root]# vi bcachefs.fio
[global]
direct=1
thread=1
norandommap=1
group_reporting=1
time_based=1
ioengine=io_uring
rw=randwrite
bs=4096
runtime=20
numjobs=1
fixedbufs=1
hipri=1
registerfiles=1
sqthread_poll=1
[filename0]
size=1G
iodepth=1
cpus_allowed=20
filename=/mnt/bcachefs/test
The option "hipri=1" need to support IORING_SETUP_IOPOLL for io_uring
engine.
