Hi,

I was looking into the bdev IO code path, and found this
in_submit_request flag, which seems to have been set every time we do
an IO submission, which makes sense considering the name of the flag.

But, in the function _spdk_bdev_io_submit(), the flag
in_submit_request is being set before the conditional "if" statement,
and depending on the conditions of the statement, it can also call
*_io_complete(). So, should the flag in_submit_request be set to true,
while called the *_io_complete() function here?

Also, can someone shed some more light on the significance of this
in_submit_request flag.
