Subject: [PATCH v2] f2fs: enable nowait async buffered writes
Date: Tue, 13 Jun 2023 15:29:11 +0800	[thread overview]
Message-ID: <20230613072912.52249-1-frank.li@vivo.com> (raw)

This adds the async buffered write support to f2fs,
the following is the relevant test data.

iodepth      | 1    | 2    | 4    | 8    | 16   |
before(M/s)  | 1012 | 1133 | 894  | 981  | 866  |
after(M/s)   | 1488 | 1896 | 2081 | 2188 | 2207 |

The following is the fio configuration:

[global]
ioengine=io_uring
sqthread_poll=1
threads=1
iodepth=32
hipri=0
direct=0
fixedbufs=0
uncached=0
nowait=0
