Subject: [PATCH] Document kernel taint flags properly
Date: Fri, 17 Oct 2008 15:55:15 -0700	[thread overview]
Message-ID: <20081017225515.GA14133@kroah.com> (raw)

From: Greg Kroah-Hartman <gregkh@suse.de>

This fills in the documentation for all of the current kernel taint
flags, and fixes the number for TAINT_CRAP, which was incorrectly
described.
