Date: Tue, 17 May 2011 17:00:05 +0530 From: Pavan Savoy <pavan_savoy@...y.com> To: Steven Rostedt <rostedt@...dmis.org> Cc: Alan Cox <alan@...rguk.ukuu.org.uk>, linux-kernel@...r.kernel.org Subject: Re: locks inside receive_buf <snip....> Well apparently I can't sleep long enough, as in from inside the tty_receive() I cannot do a tty->ops->write and wait for receive() - since there is 1 receive_buf for 1 tty .... Well I do have a requirement, where I must send some data from inside the receive_buf function of a line discipline driver wait for a certain kind of response and then proceed doing something else. scheduling a work upon the default worker thread also doesn't seem to be helping and the tty_receive() handler is called only after the wait inside the work struct handler is done... So any suggestions? should I create a new worker thread ? or any thing simpler ? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
