I assume you're trying to keep these diffs as small as possible, but I
imagine at some point the above can also be combined into a single
mod_timer.

Also, all the goofiness with the flags stuff seems like an antique
replacement for timer_pending:

>        conn->nopin_response_timer_flags |= ISCSI_TF_RUNNING;
