After enabling this feature, the read performance has been greatly
improved:
167M/s -> 234M/s, Increase ratio by 40%
Test w/:
./fio --name=onessd --filename=/data/test/local/io_uring_test
--size=256M --rw=randread --bs=4k --direct=0 --overwrite=0
--numjobs=1 --iodepth=1 --time_based=0 --runtime=10
--ioengine=io_uring --registerfiles --fixedbufs
--gtod_reduce=1 --group_reporting --sqthread_poll=1
