How does FIO detect write errors when ioengine is libaio

["Scott Forman (scforman)" <scforman@xxxxxxxxx>]

Hi,

I am trying to determine how fio detects write errors when the ioengine is set to libaio.

>From a code example on stack overflow, linux-kernel-aio-functionality, it appears that they can be detected by examining the events returned from io_getevents().

But I do not see any code in libaio.c that examines the events returned from io_getevents().

Can you verify that fio does check for write errors for engine libaio, and if so, where that error checking is done?

Thanks in advance!

Sincerely,

Scott Forman
