rf_markalldirty() needs to update the mod_counter for used_spares too!
...
This bug appears as "incorrect Mod Counters" in 'raidctl -s'. The
reason it was seen only in 'raidctl -s' is because of the conditions
needed to trigger the bug:
a) a raid set is configured
b) no partitions on that set are mounted or are otherwise in-use
c) a component is failed, and subsequently rebuilt to a hot spare
d) the machine is rebooted while something (e.g. 'raidctl -s') has
the device open (and, therefore, rf_markalldirty() has been called)
but before the final rf_update_component_labels() is done.
Needless to say, the window for this happening is *very* small, and it
was only because I was testing some obscure stuff that I even noticed it.

unfortunately, due to multiple bugs, this will cause new kernels and old

As part of the effort to get RAIDframe playing nicely with LOCKDEBUG,
...
rework how completed requests are handled. In particular, instead of
doing all sorts of work and locking in interrupt context, completed
requests are now queued. A new kernel thread (rf_RaidIOThread) now
handles calling rf_DiskIOComplete() and (req->CompleteFunc)() for each
completed request. There is still work to be done to make RAIDframe
LOCKDEBUG friendly, but this change is a huge step forward.

Merge the gehenna-devsw branch into the trunk.
...
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

Pool deals fairly well with physical memory shortage, but it doesn't
...
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map). Try to deal with this:
* Group all information about the backend allocator for a pool in a
separate structure. The pool references this structure, rather than
the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
to become available, but will still fail if it cannot callocate KVA
space for the pages. If this happens, carefully drain all pools using
the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
some pages, and use that information to make draining easier and more
efficient.
* Get rid of PR_URGENT. There was only one use of it, and it could be
dealt with by the caller.

code is used for more than anticipated, and I missed a few checks last
night. Thanks to Bernd Ernesti for poking me about this.

Nobody calls these bits if we arn't doing RAID5 with rotated spare stuff.
...
Add an #if.

These bits are only needed for the interdecluster stuff.. wrap them
...
with an #if.

Whoops.. Leave them on.. (for now.)

Give the parity declustering code their own 'RAID arch' types, and
...
allow us to turn them off if desired.

Lots of stuff here that is only used for some of the 'fancier' RAID types.
...
Don't compile it if we arn't going to use it.

Clean up some INDENT warnings. (yes, these have been there for a while!)

Various parts of this file are only needed by the even/odd and PQ
...
RAID types. Don't include those bits if we arn't doing even/odd or PQ stuff.

Don't build the stuff in this file if RF_INCLUDE_EVENODD is not defined.

Ensure we update the 'partitionSize' field of the component labels
...
when doing a reconstruct or a copyback. If we don't, junk might be
there, and that could cause the component to be not correctly
autoconfigured on reboot. Thanks to Simon Burge for helping track this down.

Return error in the case of using ODIOCGDINFO or ODIOCGDEFLABEL when
...
the number of partitions is > OLDMAXPARTITIONS. This is better
than silently truncating the label (don't want to silently throw
away partitions when using an old disklabel binary on a label with
> 8 partitions). From Enami Tsugutomo.

Adapt all disk devices in MI directories to handle ODIOC* calls
...
for ports that have bumped MAXPARTITIONS (and thus define
__HAVE_OLD_DISKLABEL).

For the RF_ASSERT() and RF_PANIC() macros, call a function to do the
...
sprintf, instead of doing the sprintf in the macros. This means just
1 copy of each of the error messages, chopping about about 16K off the
size of an i386 kernel. Thanks to Simon Burge and Enami Tsugutomo
for providing the inspiration to do this.

Fix a couple of warnings about uninitialized variables. Thanks go to
...
Frank van der Linden for pointing these out.

Comment out 2 cases of unitialized variable use (only used when
...
debugging is switched on, though).

c62d17a551
rationalize the use of b_flags for geteblk() buffers.
...
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.

Move disk_busy() and disk_unbusy() to more sane locations. Values
...
reported by 'systat iostat' and friends are now much more correct for
RAIDframe devices. Thanks to Andrew Doran for poking me about this,
and for suggestions on and review of the changes.

Don't touch a failed component at all. Thanks to Robert Elz (kre) for
...
noting the problem and providing additional comments.

Minor fixup for a printf(). Noted by Robert Elz.

convert tsleep()->ltsleep(), which makes the kernel complain less
...
when compiled with LOCKDEBUG.

Correct a few calls to VOP_CLOSE().
