From ee40fecafe349fcfed42b164885e6c079e8e1485 Mon Sep 17 00:00:00 2001 From: cem Date: Tue, 13 Aug 2019 20:06:55 +0000 Subject: [PATCH] Remove deprecated GEOM classes Follow-up on r322318 and r322319 and remove the deprecated modules. Shift some now-unused kernel files into userspace utilities that incorporate them. Remove references to removed GEOM classes in userspace utilities.
