I tested Andreas patches from v2 to v6 and aiocp with -f DIRECT works only on
btrfs. Running on $TMPDIR being on ext4, xfs, tmpfs endup with EINVAL:

# ./aiocp -b 1k -n 1 -f DIRECT
aiocp.c:240: TINFO: Maximum AIO blocks: 65536
aiocp.c:265: TINFO: Fill srcfile.bin with random data
aiocp.c:267: TBROK: open(srcfile.bin,16450,0666) failed: EINVAL (22)

Any idea what could be wrong?

Kind regards,
Petr
