138cedfdc6 - Show all commands in usage, even if those commands are not available. 
- When command is not available, just say it, instead of says, that command
  is unknown. Old behaviour seems to be too confusing.

edcf2d2891 When configuring RAID3 with verification option, force synchronization

dba915cfee Implementation of 'verify reading' algorithm, which uses parity data for 
verification of regular data when device is in complete state.
On verification error, EIO error is returned for the bio and sysctl
kern.geom.raid3.stat.parity_mismatch is increased.

f5a2f7feac Implement new reading algorithm, which will use parity component for reading 
as well, even if device is in complete state.
I observe 40% of speed-up with this option for random read operations,
but slowdown for sequential reads.
Basically, without this option reading from a RAID3 device built from 5
components (c0-c4) looks like this:

	Request no.	Used components
	1		c0+c1+c2+c3
	2		c0+c1+c2+c3
	3		c0+c1+c2+c3

With the new feature:

	Request no.	Used components
	1		c0+c1+c2+c3
	2		(c1^c2^c3^c4)+c1+c2+c3
	3		c0+(c0^c2^c3^c4)+c2+c3
	4		c0+c1+(c0^c1^c3^c4)+c3
	5		c0+c1+c2+(c0^c1^c2^c4)
	6		c0+c1+c2+c3

c38d2f4eca Forgot to commit those: introduce hardcoded provider functionality,

6c74f5177c - Introduce option for hardcoding providers' names into metadata. 
It allows to fix problems when last provider's sector is shared between few
  providers.
- Bump version number for CONCAT and STRIPE and add code for backward
  compatibility.
- Do not bump version number of MIRROR, as it wasn't officially introduced yet.
  Even if someone started to play with it, there is no big deal, because
  wrong MD5 sum of metadata will deny those providers.
- Update manual pages.
- Add version history to g_(stripe|concat).h files.

32e7be7043 After changing LIBDIR to SHLIBDIR, because of dependencies problems, 
new problem shows up: symblic links (<libname>.so) are created under
/usr/lib/ now, instead of under /lib/geom/ where geom(8) looks for them.
Introduce a workaround to fix this by teaching geom(8) to open libraries
via /lib/geom/<libname>.so.<major_number> instead of /lib/geom/<libname>.so.

d5c96d389e - Add '-S' option, which allow to specify sector size for transparent 
provider.
- Bump version number.

This allows for a quite interesting trick. One can setup a stripe with
stripe size of 512 bytes and create transparent provider on top of it
with sector size equal to <ndisks> * 512. The result will be something
like RAID3 without parity disk (every access will touch all disks).
