Subject: [PATCH v3 0/4] fsstress,fsx: add io_uring test and do some fix
Date: Sun, 23 Aug 2020 14:30:28 +0800	[thread overview]
Message-ID: <20200823063032.17297-1-zlang@redhat.com> (raw)

This patchset tries to add new IO_URING test into fsstress [1/4] and fsx [4/4].
And then do some changes and bug fix by the way [2/4 and 3/4].

fsstress and fsx are important tools in xfstests to do filesystem I/Os test,
lots of test cases use it. So add IO_URING operation into fsstress and fsx
will help to cover IO_URING test from fs side.

I'm not an IO_URING expert, so cc io-uring@ list, please feel free to
tell me if you find something wrong or have any suggestions to improve
the test.

V2 did below changes:
1) 1/4 change the definition of URING_ENTRIES to 1
2) 2/4 change the difinition of AIO_ENTRIES to 1, undo an unrelated changed line
3) 4/4 turn to use io_uring_prep_readv/io_uring_prep_writev, due to old
       liburing(0.2-2) doesn't support io_uring_prep_read/io_uring_prep_write.

V3 changed io_uring_submit(&ring) to io_uring_submit_and_wait(&ring, 1). I'm
not sure if this's the real mean of Jens Axboe's review point, please check.
