Hi all,
the gdth driver has long seen no updates, and has a very peculiar
coding style.
Here's an attempt to (slowly) move it towards the linux coding style,
and fixup some oddities within the driver itself.
Adaptec has been defunct for several years now, so I doubt the maintainer
address is still working; so I'll leave it out for now.
Achim, if you are still around, do speak up :-)
As usual, comments and reviews are welcome.
Hannes Reinecke (4):
gdth: reindent and whitespace cleanup
gdth: do not use struct scsi_cmnd as argument for bus reset
gdth: kill __gdth_execute()
gdth: stop abusing ->request pointer for completion

Long overdue. No functional change.

Bus reset just needs the number of the bus to reset as argument,
so introduce a function gdth_bus_reset() and avoid allocating
a temporary scsi command when bus reset is triggered via ioctl.

gdth_execute() is just a wrapper around __gdth_execute(), which
tries to allocate the host device, too.
But the host device is required for other code paths, too, so
we should allocate it during pci init, kill the original
gdth_execute() and rename __gdth_execute() to gdth_execute().

Do not overload the request point for completion but rather use
a dedicated field in the cmndinfo structure.

Did you test if compiler generates the same output? I don't think anyone
wants to review this patch :)

Phew. Just checked, and the disassembly is indeed identical.

I am not really convienced it is a good idea to reformat the whole
driver at this point. Sure, checkpatch.pl & friends will be more
happy with new changes. Though, in 10 years there were only 44
changes and I don't think there will be a lot more in the coming
years. Just my thoughts.

As mentioned, the gdth driver is the only one using the scsi_host_dev
feature, which I'll be improving/updating with my reserved tags for SCSI
patchset.
And to avoid my eyes falling out everytime I need to look at the driver
I would very much prefer to have the reindent done.
Especially as it can be easily verified.
Cheers,
Hannes

Do you actually have a gdth card? Do we know of other users?
Maybe just dropping the driver might be a better option..

Yes, no, and possibly :-)
The gdth hardware is based on the i960 chip, and has borrowed quite some
concepts for the now-defunct I2O design.
Plus it's PCI and SCSI parallel only, so it took me quite some time to
find a machine where I could fit both in.
So I do agree that this could be classified as obsolete, much like we
did with the I2O subsystem some years back.
Would actually save me quite some time, as the driver itself is really
just too ugly to behold in its current state.
And bringing it into this century would amount to basically a rewrite.
Cheers,
Hannes
