From b0a9c5ccf31514630755e9a5d15204a55a47740f Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Fri, 7 Oct 2011 23:01:55 +0200 Subject: mptable: Refactor mptable generation some more The last couple of lines of every mptable function were mostly identical. Refactor into common code, a new function mptable_finalize.
