>> If stgt is restricted to page size transfers, then it should set the
hardware block size to that (which would then cause fio with 2k bs and
O_DIRECT to error out, instead of crash).
Hi Jens,
Block size is not an issue. I can use other ioengine (like sync) to run thru the test with bs=2k & under, only libaio ioengine has this problem.
Besides, when I run fio with "--ioengine=sync" and "--iodepth=64", the initiator immediately crash. I know iodepth is only matter to aio type, but it shouldn't crash the kernel.
