Re: [patch] xenfb: fix xenfb suspend/resume race

No, it papers over the issue, the code should never have been allowed to
get this far if the connection to the backend is not yet fully resumed
(i.e. when irq = -1).

The call to xenfb_send_event should have been gated further up the call
chain, AFAICT by the check of info->update_wanted in xenfb_refresh. This
suggests that the correct fix is to set info->update_wanted = 0 in
xenfb_resume.

I said all this in my previous mail and you ignored it. Did you try this
approach?

Will try this then update you.

Thanks,
