From db9c02fa8bd50eb104781a9f78cae923d8da1e74 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Tue, 8 May 2007 00:30:17 -0700 Subject: pnpbios: convert to use the kthread API This patches modifies the pnpbios kernel thread to start with ktrhead_run not kernel_thread and deamonize. Doing this makes the code a little simpler and easier to maintain. Signed-off-by: Eric W.
