a9d129e2f3 Clean up comments.
Don't return "can't do it" when the user requests a state change to
the current state.  This previously caused silly messages like "Can't
start <foo>: invalid argument", when in fact <foo> was already
started.

set_plex_state: don't set state for non-existent plexes.

update_plex_status: as long as we have initializing subdisks, we're
		    initializing.

942707108f Clean up some comments.
Move the declaration of freerq() to request.h.

logrq: add support for lock events.

vinumstart: solve a problem where removing a plex from an active
	    volume could cause attempts to access non-existent plexes.

launch_requests: don't set a request group active until we're sure we
		 can launch it.  This caused some hangs under unusual
		 circumstances.

bre: don't set XFR_BAD_SUBDISK if we're not going to use it.

build_read_request: correct recovery, which caused some hangs under
		    (other) unusual circumstances.

build_rq_buffer: don't set bp->b_dev if we don't have a dev.

sdio: clean up, remove obsolete code.

deallocrqg: unlock any locks the rqg may have.

  Shorten some lines.

  Desired-by:  bde

  If we're reading from a short plex, return EOF indication.

  Always lock the stripe before starting a transfer.  Hopefully the
  current version will solve some data integrity problems that have
  been reported with degraded RAID-5 plexes.

f8c6eb66f7 Remove some XXX comments (they're not really gone, just invisible).
Tidy other comments.

open_drive: don't call set_drive_state if we decide to take it down.
This could help avoid some race conditions with the daemon.

init_drive: don't set the drive down, we'll let close_locked_drive do
that.

close_locked_drive: set drive state to down without calling
set_drive_state.  This could help avoid some race conditions with the
daemon.

driveio: remove the function, it wasn't being used.

get_volume_label: remove volume dependencies so that we can return a
label for plexes and subdisks as well.  What a kludge.

checkdiskconfig(): remove.  It didn't make any sense to complain about
kernel keywords in user config files; it just made it more difficult
to convert.  Now we ignore kernel keywords if we're not in kernel
mode.

get_empty_sd: initialize sectors.

free_drive: don't close if we don't have a vp.  Maybe this will help
fix the problem that peter had, but I wouldn't count on it.

config_plex: If the plex is RAID-5, give it a rangelock structure.

'create' command doesn't get long-dead defaults.

a8658ef38f Grrrr. Fix a really lame bug that I tripped over while testing my miibus
stuff: unregister_methods() is horribly broken. The idea, if I'm not mistaken,
is that the refcount on a method is decremented, and only when it reaches
zero is the method freed. However desc->method is set to NULL unconditionally
regardless of the refcount, which means the method pointer is trashed the
first time the method is deallocated. The obvious detrimental effect is
that memory is leaked. The not so obvious effect is that when you call
unregister_method() the second time on the same method, you get a NULL
pointer dereference and a panic.

Now I can successfully unload network device drivers and the miibus module
without crashing the system.

*sigh*

No one's objected, so I've made this change.  This sort of fixes docs/12220,
by removing the reference to the undocumented getkerninfo(2) call.  So I'll
close the PR as well.

17f88167e4 Make the default page coloring parameters match a (non-Xeon) Pentium II/III.
This setting is also acceptable for Celerons and Pentium Pros
with less than 1MB L2 caches.

Note: PQ_L2_SIZE is a misnomer.  The correct number of colors is
a function of the cache's degree of associativity as well as its size.
