From 9159c9dfffe1746d58b015ceaa3b7b8e99ee9d5c Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Fri, 6 Jan 2006 00:18:58 -0800 Subject: [PATCH] [PATCH] uml: Fix flip_buf full handling When the tty flip_buf is full, it's a good idea to delay the input processing for a jiffy, rather than just scheduling the tasklet immediately.
