From 46c271bedd2c8444b1d05bc44928beec0c07debc Mon Sep 17 00:00:00 2001 From: Peter Osterlund <petero2@telia.com> Date: Thu, 23 Jun 2005 00:10:02 -0700 Subject: [PATCH] Improve CD/DVD packet driver write performance This patch improves write performance for the CD/DVD packet writing driver. The logic for switching between reading and writing has been changed so that streaming writes are no longer interrupted by read requests.
