From d5dc0ae4df9db00b8122378d56a071039b17a1eb Mon Sep 17 00:00:00 2001 From: Filip Aben Date: Tue, 22 Jun 2010 10:10:35 -0700 Subject: hso: remove setting of low_latency flag This patch removes the setting of the low_latency flag. tty_flip_buffer_push() is occasionally being called in irq context, which causes a hang if the low_latency flag is set. Removing the low_latency flag only seems to impact the flush to ldisc, which will now be put on a workqueue. Signed-off-by: Filip Aben Signed-off-by: David S.
