Subject: [PATCH 0/8] PNP debugging rework
Date: Tue, 19 Aug 2008 16:53:10 -0600 [thread overview]
Message-ID: <20080819225310.28206.1011.stgit@tigger.helgaas> (raw)
These patches add support for a boot-time switch to enable PNP debug
messages. Currently, users have to recompile with CONFIG_PNP_DEBUG=y
to get PNP debug messages.
I copied the implementation strategy from Greg KH's USB patches:
http://lkml.org/lkml/2008/8/8/529
These patches don't fix any bugs, and I know it's pretty late to
consider new stuff for 2.6.27. The only reason to even consider them
is that 2.6.27 includes a significant PNP rewrite, and if 2.6.27 ends
up in a distro kernel, it will be much easier to work on problems if
users can collect debug information without rebuilding the kernel.
