Subject: [PATCH] cleanup virtual console <-> selection.c interface
From: Christoph Hellwig <hch () lst ! de>
Date: 2004-12-31 14:34:57
Message-ID: 20041231143457.GA9165 () lst ! de
[Download RAW message or body]
Pass around pointers instead of indices into a global array between
various files of the virtual console implementation and stop using
obsfucting macros that expect certain variables to be in scope.
This is a first step to get rid of the various global arrays in the VC
code.
