Roland, I need to recall this patch. It appears to have some problem.
Good thing I didn't apply it yet.
I did think it should be possible to declare wait objects on the stack... the
origin of completions was to handle exactly that issue; the older semaphore
structure was vulnerable to the wakeup after free, but completions handle
that. But I didn't look at the cxgb4 code at all...
I'm pretty sure the race exists as described in my commit comment. And I don't see how the wait object code could avoid
this issue. Unless I'm just all wrong. :)
