ltp-aio-stress.part[12] have been merged due to tests duplication and
new ltp-aio-stress test rewrite that doesn't require $TMPDIR parameter
anymore.

Maybe just:
"Test opens or creates ..."
I'd personally put blank line before starting multiline comment, before opening
if, below } - ending if and return before the end of function (readability). But
you can ignore these.

Why this? io_getevents() takes now 4 args, man does not mention when it was
changed. I'd delete this definition and #else.

How about use ARRAY_SIZE()?

This should be without ", default is run until Cntl-C".
OT: Cntl looks trange to me, I'd use ^C or <ctrl> + C (irrelevant now)
I also see RUN_FOREVER, do we really need it? No other LTP test runs forever.

I haven't looked into what might be causing that, but you could try
compiling and running it with the address sanitizer.
Also if I pass -f DIRECT it fails with EINVAL.

Thank you,

Maybe this part would be a bit better with goto as:
if (oper->rv == WRITE && (staves & (1 << READ))) {
new_rw = READ;
goto restart;
}
if (oper->rv == READ && (stages & (1 << RWRITE))) {
new_rw = RWRITE;
goto restart;
}
...
restart:

This is now length not offset, also now the size we pass to the write
varies between 0 and bufsize/2. Shouldn't we rather go for a size
between bufsize/2 and bufsize?
len = rand() % (bufsize/2) + bufsize/2;
towrite = MIN(len, size-i);

- * version of copy command using async i/o
- * From: Stephen Hemminger <shemminger@osdl.org>
- * Modified by Daniel McNeil <daniel@osdl.org> for testing aio.
- * - added -a alignment
- * - added -b blksize option
- * _ added -s size option
- * - added -f open_flag option
- * - added -w (no write) option (reads from source only)
- * - added -n (num aio) option
- * - added -z (zero dest) opton (writes zeros to dest only)
- * - added -D delay_ms option
- *
- * Copy file by using a async I/O state machine.
- * 1. Start read request
- * 2. When read completes turn it into a write request
- * 3. When write completes decrement counter and free resources
