 1.29  23-Jul-2021  oster Extensive mechanical changes to the pools used in RAIDframe.

Alloclist remains not per-RAID, so initialize that pool
separately/differently than the rest.

The remainder of pools in RF_Pools_s are now per-RAID pools. Mostly
mechanical changes to functions to allocate/destroy per-RAID pools.
Needed to make raidPtr available in certain cases to be able to find
the per-RAID pools.

Extend rf_pool_init() to now populate a per-RAID wchan value that is
unique to each pool for a given RAID device.

TODO: Complete the analysis of the minimum number of items that are
required for each pool to allow IO to progress (i.e. so that a request
for pool resources can always be satisfied), and dynamically scale
minimum pool sizes based on RAID configuration.
 1.28  10-Feb-2019  christos branches: 1.28.16;
Introduce PR_ZERO to avoid open-coding memset()s everywhere. OK riastradh@.
 1.27  09-Feb-2019  christos - Change the allocation macros to be more like function calls
- Change sizeof(type) -> sizeof(*variable)
- Use macros for the long buffer length allocations
- Remove "bit polishing" memsets() -- do them only once
- Remove unnecessary casts

Thanks to oster@ for finding bugs and testing.

ansify function definitions
 1.25  16-Nov-2006  christos branches: 1.25.52; 1.25.62; 1.25.68;
__unused removal on arguments; approved by core.
 1.24  12-Oct-2006  christos - sprinkle __unused on function decls.
- fix a couple of unused bugs
- no more -Wno-unused for i386
 1.23  11-Dec-2005  christos branches: 1.23.20; 1.23.22;
merge ktrace-lwp.

- Introduce rf_pools which contains all of the various global pools used
by RAIDframe. Convert all other RAIDframe global pools to use pools
defined within this new structure.
- Introduce rf_pool_init(), used for initializing a single pool in
RAIDframe. Teach each of the configuration routines to use
rf_pool_init().
- Cleanup a few pool-related comments.
- Cleanup revent initialization and #defines.
- Add a missing pool_destroy() for the reconbuffer pool.

(Saves another 1K off of an i386 GENERIC kernel, and makes
stuff a lot more readable)

 1.19  05-Mar-2004  oster - remove the RF_*_INC's, as necessary. They are not needed any more.
- introduce RF_MIN_*'s, as necessary. These will indicate the
low-water mark for pools as well as the pool_prime() value.
- add pool_setlowat() for the critical pools.
- pool_prime() and pool_setlowat() the raidframe_cbufpool.
- re-order some pool_prime()'s and pool_sethiwat()'s for clarity.
 1.18  29-Feb-2004  oster Adjust _rf_ShutdownCreate() so that it is willing to wait for more
memory. Since we only now ever "return(0)", just return (void)
instead.

Cleanup all uses of rf_ShutdownCreate() to not worry about
it ever failing. Shaves another 600 bytes off of an i386 GENERIC kernel.
 1.17  25-Feb-2004  oster Poolify alloclist stuff. Saves a whopping 32 bytes while decreasing code
complexity.
 1.16  31-Dec-2003  oster Replace the DO_FREE() macro with just RF_Free(). No functional changes,
just less confusion.
 1.15  30-Dec-2003  oster Some days you wonder if some of the function declaration consistency
was just an accident in the first place. Cleanup function decls and
a few comments. [ok.. so I wasn't going to fix this many.. but once
you're on a roll....]
 1.14  01-Jul-2003  oster branches: 1.14.2;
Actually toss the comment I said I was tossing in the last commit.
 1.13  01-Jul-2003  oster - toss a comment that is no longer relevant.
- alist_mutex is a holdover from the simulator days, and it
wasn't even used back then. Toss the variable and init/destroy calls.
 1.12  01-Jul-2003  oster Minor cleanup. No functional changes.
 1.11  23-Sep-2002  oster Nuke 'lockflag', a holdover from the simulation code. Thanks to Simon B.
 1.10  14-Sep-2002  oster Everyone and their dog was using RF_ERRORMSG3 to print out the same
sort of error message, over and over again, in different files.
Rather than having the same text repeated in multiple .o files,
create a couple of little functions to do the printing, and save a
bundle of space. Also improves readability of code.
 1.9  20-Nov-2001  oster Cleanup some whitespace that indent got wrong a long time ago.
 1.8  13-Nov-2001  lukem add RCSIDs
 1.7  04-Oct-2001  oster If rf_options.h needs to be include it, then include it. Don't rely on
another .h file to pull it in.
 1.6  04-Oct-2001  oster Step 2 of the disentanglement. We now look to <dev/raidframe/*> for
the stuff that used to live in rf_types.h, rf_raidframe.h, rf_layout.h,
rf_netbsd.h, rf_raid.h, rf_decluster,h, and a few other places.
Believe it or not, when this is all done, things will be cleaner.

No functional changes to RAIDframe.

bzero -> memset
 1.4  13-Aug-1999  oster branches: 1.4.14; 1.4.16;
rf_sys.h does not need to be #included in any of these files, and, actually,
is no longer needed at all.
 1.3  05-Feb-1999  oster Phase 2 of the RAIDframe cleanup. The source is now closer to KNF
and is much easier to read. No functionality changes.
 1.2  26-Jan-1999  oster RAIDframe cleanup, phase 1. Nuke simulator support, user-land driver,
out-dated comments, and other unneeded stuff. This helps prepare
for cleaning up the rest of the code, and adding new functionality.

No functional changes to the kernel code in this commit.
 1.1  13-Nov-1998  oster RAIDframe, version 1.1, from the Parallel Data Laboratory at
Carnegie Mellon University. Full RAID implementation, including
levels 0, 1, 4, 5, 6, parity logging, and a few other goodies.
Ported to NetBSD by Greg Oster.
