Make better checks that the revive block size is valid, silently set
it to the defaults if not.
Replace block device macros with generalized device macros.
avoids a race condition where multiple RAID-5 subdisks are being
revived at the same time. The locks should also prevent conflicts
with user requests on concatenated and striped plexes, but this needs
more work.
Tidy up some comments.
lockmgr locks. This commit should be functionally equivalent to the old
semantics. That is, all buffer locking is done with LK_EXCLUSIVE
requests. Changes to take advantage of LK_SHARED and LK_RECURSIVE will
be done in future commits.
kernel as a pseudo-device. The changes were:
- #ifdef DEBUG -> #ifdef VINUMDEBUG
- opt_vinum.h for holding above config variable
- Fixing up a few stray problems where DEBUG wasn't optional.
- config.c -> vinumconfig.c (there's already a config.o)
- Other *.c -> vinum*.c (wasn't strictly necessary, but done in case we end
up with something else conflicting later on and we might have to have yet
more repository copies of files).
- include file paths fixups.. (ie: get them all from the kernel tree
instead of partly from the kernel and partly from /usr/include/machine)
I've spoken with Greg about this.. I hope this doesn't mess him around
too much..
