[PATCH 0/3] xfstests: new io_uring fsx test

[PATCH 0/3] xfstests: new io_uring fsx test

[Zorro Lang]

This patchset bases on https://patchwork.kernel.org/cover/11769847/, which
makes xfstests fsstress and fsx supports IO_URING.

The io_uring IOs in fsstress will be run automatically when fsstress get
running. But fsx need a special option '-U' to run IO_URING read/write, so
add two new cases to xfstests to do fsx buffered and direct IO IO_URING
test.

[1/3] new helper to require io_uring feature
[2/3] fsx buffered IO io_uring test
[3/3] fsx direct IO io_uring test

And the [2/3] just found an io_uring regression bug (need LVM TEST_DEV):
https://bugzilla.kernel.org/show_bug.cgi?id=209243

Feel free to tell me, if you have more suggestions to test io_uring on
filesystem.

Thanks,
Zorro

[PATCH 1/3] src/feature: add IO_URING feature checking

[Zorro Lang]

IO_URING is a new feature for GNU/Linux system, if someone case of
xfstests tests this feature, better to check if current system
supports it, or need _notrun.

Funny, I would have expected this to be a clone of generic/521, much
like the previous test was a clone of g/522.  I guess it's fine to test
various fsx parameters, but in that case, is there a reason /not/ to
have a long soak io_uring directio test?

Can you elaborate on why PSIZE/BSIZE are used where they are for the
writebdy option? Also is -R intentionally dropped from the final test?
