If anyone has any objections, please let us know. ------------------ From: Chuck Ebbert commit 4d8d4d251df8eaaa3dae71c8cfa7fbf4510d967d upstream [ cebbert@redhat.com: backport to 2.6.27 ] Remove low_latency flag setting from nozomi and mxser drivers The kernel oopses if this flag is set. [and neither driver should set it as they call tty_flip_buffer_push from IRQ paths so have always been buggy] Signed-off-by: Chuck Ebbert Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman --- --- drivers/char/mxser.c | 2 -- drivers/char/nozomi.c | 1 - 2 files changed, 3 deletions(-) --- a/drivers/char/mxser.c +++ b/drivers/char/mxser.c @@ -1099,8 +1099,6 @@ static int mxser_open(struct tty_struct if (retval) return retval; - /* unmark here for very high baud rate (ex. 921600 bps) used */ - tty->low_latency = 1; return 0; } --- a/drivers/char/nozomi.c +++ b/drivers/char/nozomi.c @@ -1584,7 +1584,6 @@ static int ntty_open(struct tty_struct * /* Enable interrupt downlink for channel */ if (port->tty_open_count == 1) { - tty->low_latency = 1; tty->driver_data = port; port->tty = tty; DBG1("open: %d", port->token_dl); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
