From 8b2b5c217c20b5460218ab8731295f2e46c7dd29 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Tue, 31 Mar 2009 14:27:03 +1100 Subject: [PATCH] md: move LEVEL_* definition from md_k.h to md_u.h .. as they are part of the user-space interface. Also move MdpMinorShift into there so we can remove duplication. Lastly move mdp_major in. It is less obviously part of the user-space interface, but do_mounts_md.c uses it, and it is acting a bit like user-space.
