From d1871b38fccdc4b6575b0cabdea9e06bc70167eb Mon Sep 17 00:00:00 2001 From: Jason Wessel Date: Sun, 26 Aug 2012 21:43:12 -0500 Subject: [PATCH] kdb: Fix dmesg/bta scroll to quit with 'q' If you press 'q' the pager should exit instead of printing everything from dmesg which can really bog down a 9600 baud serial link. The same is true for the bta command.
