linux.git/drivers/usb/serial/visor.c, branch v2.6.30 Linux kernel source tree USB: removal of tty->low_latency hack dating back to the old serial code 2009-04-23T21:15:29+00:00 Oliver Neukum oliver@neukum.org 2009-04-20T15:28:53+00:00 2400a2bfbd0e912193fe3b077f492d4980141813 This removes tty->low_latency from all USB serial drivers that push data into the tty layer at hard interrupt context. It's no longer needed and actually harmful. Signed-off-by: Oliver Neukum <oliver@neukum.org> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

This also gives us a framework for general tty drivers to use tty_port objects and refcount. Contains two err->dev_err changes merged together to fix clashes in the -next tree.

usb_serial: API all change 2008-07-22T20:03:22+00:00 Alan Cox alan@redhat.com 2008-07-22T10:09:07+00:00 95da310e66ee8090119596c70ca8432e57f9a97f USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process. Longer term we need a proper tty as console abstraction Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
