Do you have the file:

/lkp/benchmarks/xfstests/results//generic/299.full

produced by the failed test? Thanks!

Sorry, we don't collect that data during regular regression test.  Is
that needed all the time?  We will change our test scripts to collect
that data.  But that need some time.

I found we have this feature in our test scripts already, just need to
fix a bug in script, but that is just done yesterday!  Please check the
299.full attached.

Thanks for the file. The cause of failure is ENOMEM error aio-dio-verifier
got - so it is very likely unrelated to my patch:

fio: io_u.c:1315: __get_io_u: Assertion `io_u->flags & IO_U_F_FREE' failed.
fio: pid=607, got signal=6
fio: io_u error on file /fs/scratch/aio-dio-verifier: Cannot allocate memory
     read offset=8446353408, buflen=4096
fio: io_u error on file /fs/scratch/aio-dio-verifier: Cannot allocate memory

  cpu          : usr=0.00%, sys=0.10%, ctx=42, majf=0, minf=14

     complete  : 0=0.0%, 4=100.0%, 8=0.0%, 16=0.0%, 32=0.0%, 64=0.0%, >=64=0.0%

     errors    : total=0, first_error=0/<Success>

If you have time, you can check why ENOMEM actually happens in your test
setup...
