From 08bbcfe72fdb6314543015e5a8831a6ff7dff417 Mon Sep 17 00:00:00 2001 From: gj Date: Mon, 3 Apr 2000 19:54:33 +0000 Subject: Nuke csu_hdr from struct cspace. csu_hdr is not used anywhere in the tree. This considerably reduces unnecessary bloat in struct slcompress. I'm running with this change right now and have seen no negative side-effects. On my sytem this reduced kernel BSS by about 25KB.
