parentmd: move LEVEL_* definition from md_k.h to md_u.h (diff)
md: move most content from md.h to md_k.h
The extern function definitions are kernel-internal definitions, so they belong in md_k.h The MD_*_VERSION values could reasonably go in a number of places, but md_u.h seems most reasonable. This leaves almost nothing in md.h. It will go soon. Signed-off-by: NeilBrown <neilb@suse.de>
