7ea810fefd Teach NOP GEOM class how to gather the following statistics: 
- number of read I/O requests,
- number of write I/O requests,
- number of read bytes,
- number of written bytes.
Add 'reset' subcommand for resetting statistics.

76d2723d97 g_nop_create: destroy newly created provider in case of errors. 2004-09-16 15:28:48 +00:00

596d3e1549 NOP class doesn't operate on metadata, so the spoil event can be safely 
ignored.

889eca7e19 - Fix unloading by the same way it is done in my other classes: 
set gp->softc to NULL and return ENXIO when it is NULL, so GEOM
  will not panic or hang, but unload one device on every 'unload'.
  This make 'unload' command usable, but it have to be executed
  <number of devices> + 1 times.
- Made use of 'pp' variable.

7a7cae7b30 - 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).

73a684d587 Improve geom(8)'s 'list' command to show geoms and their providers and 
consumers. Teach STRIPE, CONCAT and NOP classes about this improvement.

67d8cb396e MFp4: Add two options for gnop(8)'s 'create' command: 
-o offset - specifies where to start on the original provider
	-s size - specifies size of the transparent provider

90c2eca016 Introduce NOP GEOM class. This is totally transparent GEOM class, but 
it is very useful for tests. One is able to destroy its provider
forcibly if wants to test how other class handle such events.
One is also able to specify failure probability to check how other
classes handle I/O errors.
