b99c307a21 Rename the existing BUF_STRATEGY() to DEV_STRATEGY()
substitute BUF_WRITE(foo) for VOP_BWRITE(foo->b_vp, foo)

substitute BUF_STRATEGY(foo) for VOP_STRATEGY(foo->b_vp, foo)

This patch is machine generated except for the ccd.c and buf.h parts.

21144e3bf1 Remove B_READ, B_WRITE and B_FREEBUF and replace them with a new
field in struct buf: b_iocmd.  The b_iocmd is enforced to have
exactly one bit set.

B_WRITE was bogusly defined as zero giving rise to obvious coding
mistakes.

Also eliminate the redundant struct buf flag B_CALL, it can just
as efficiently be done by comparing b_iodone to NULL.

Should you get a panic or drop into the debugger, complaining about
"b_iocmd", don't continue.  It is likely to write on your disk
where it should have been reading.

This change is a step in the direction towards a stackable BIO capability.

A lot of this patch were machine generated (Thanks to style(9) compliance!)

Vinum users:  Greg has not had time to test this yet, be careful.

alpha.

Identify daemon as 'vinum', not 'vinumd', in messages.  This
corresponds to the name in ps.

49ff4debd3 Spring cleaning around strategy and disklabels/slices:
Introduce BUF_STRATEGY(struct buf *, int flag) macro, and use it throughout.
please see comment in sys/conf.h about the flag argument.

Remove strategy argument from all the diskslice/label/bad144
implementations, it should be found from the dev_t.

Remove bogus and unused strategy1 routines.

Remove open/close arguments from dssize().  Pick them up from dev_t.

Remove unused and unfinished setgeom support from diskslice/label/bad144 code.

e0e19a088b change printf() calls to log() calls.
Don't save config while we're reading it from disk.

Change the way we handle the daemon: if we can't communicate with it
for 1 second (which is possible), start a new one.  The daemon saves
its pid in daemonpid; on each iteration of the main loop the daemon
checks whether it's still in favour.  If not, it silently exits.
Also, when trying to communicate with the daemon, check daemonpid
first.  If it's set to 0, don't even try.

cc902735df In some cases, it's possible that I/O errors will cause the daemon to
time out on an operation.  Under these circumstances, vinum(8) will
automatically start another daemon.  Add a pid for the daemon, so that
an overtaken daemon will discover that it's no longer in favour, and
will crawl into a corner and die.
