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

fsstress is an important tool in xfstests to do random filesystem I/Os
test, lots of test cases use it. So add IO_URING operation into fsstress
will help to make lots of test cases cover IO_URING test naturally.

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.

Thanks,
Zorro
