* when we have stop/sysrq/go, we get pt_regs of whatever executes mc_work_proc(). Would be better to see what we had at the time of interrupt that got us stop. * stop/stop/stop..... will give stack overflow. Shouldn't allow stop from mconsole_stop(). * stop/stop/go leaves us inside mconsole_stop() with os_set_fd_block(req->originating_fd, 0); reactivate_fd(req->originating_fd, MCONSOLE_IRQ); just done by nested mconsole_stop(). Ditto. * once we'd seen stop, there's a period when INTR commands are executed out of order (as they should; we might have the things stuck badly enough to never reach mconsole_stop(), but still not badly enough to block mconsole_interrupt(); in that situation we _want_ things like "cad" to be executed immediately). Once we enter monsole_stop(), all INTR commands will be executed in order, mixed with PROC ones. We'd better let user see that such change of behaviour has happened. (Suggested by lennert). * stack footprint of monsole_interrupt() is an atrocity; AFAICS we can safely make struct mc_request req; static in function there.
