Hi!
following is an attempted at unified patchset for the gdth driver.
They try to incorporate floating patches to gdth from:
Christoph Hellwig
Jeff Garzik
Matthew Wilcox
and Me Boaz Harrosh
They are done in the mindset of "likelihood of inducing breakage",
hence the need for testers. Christoph & Jeff please review for any
obvious easy-to-catch bugs. Also there was a massive code shifts
and rebasing I hope nothing was lost.
The differences from last set are:
- Matthews patches are first so they can go in. They
are a bit modified so please take these and not the
original. Mainly they restrain from cleanups
- Fix Christoph bug that was spotted by jeff of the misplaced
#endif. Also when compiling with out CONFIG_{ISA,EISA,PCI}
compiler would complain about unused params, functions and
so on so fixed that.
- More Aggressive fix for gdth_interrupt() and friends
Christoph pleeeeeeease review.
- Rebasing to all above. I hope I'll get the From:
right this time
Some short explanations:
[01/16] gdth: Make one abuse of scsi_cmnd less obvious - Matthew Wilcox
[02/16] gdth: Stop abusing ->done for internal commands - Matthew Wilcox
Patches from Matthew, but cleaned for future patchability.
[03/16] gdth: split out isa probing - Christoph Hellwig
[04/16] gdth: split out eisa probing - Christoph Hellwig
[05/16] gdth: split out pci probing - Christoph Hellwig
These three are from Christoph and where ACKed by
Jeff at the time. Revised by me for warning fixes when
one of the buses ISA/EISA/PCI is not defined.
[06/16] gdth: Remove 2.4.x support, in-kernel changelog - Jeff Garzik
Same but partial work was done both by Christoph and Matthew.
[07/16] gdth: kill gdth_{read,write}[bwl] wrappers - Jeff Garzik
[08/16] Reorder scsi_host_template intitializers
[09/16] gdth: Remove virt hosts - Christoph && Boaz
Here we need an executive decision! The issue is as stated by Christoph:
"The virt_ctr option allows to register a new scsi_host for each bus
on the raid controller. This non-default option makes no sense with
the current scsi code and prevents cleaning up the host registration,
so remove it."
I agree. This is just exactly the same as done buy scsi-ml scans but only
more resource consuming. Unless I'm totally missing something, perhaps it is
just a leftover from old kernels.
[10/16] gdth: clean up host private data - Christoph && Boaz
This is based on the same patch from Christoph, but taken one step
farther, by just passing the ha pointer everywhere instead of hanum.
[11/16] gdth_interrupt gdth_get_status & gdth_wait fixes - Boaz
This logically belongs to [9/16] but is separated for reviewing and
bisect-ability As it is a sensitive matter.
It is done aggressively this time around Please review!
[12/16] gdth: switch to modern scsi host registration - Christoph
Christoph what is missing from here is the remove of the deprecated
pci_find_device() call. Can I Just use pci_get_device() of the same signature
or do I need to call some other pci_ members after that?
[13/16] gdth: Remove gdth_ctr_tab[] - Boaz
I took Christoph's cleanup one step farther and got read of the statically
allocated gdth_ctr_tab[]. In it's place I use the new link-list introduced
by the [11/16] patch.
[14/16] gdth: Setup proper per-command private data - Boaz
[15/16] gdth: Move members from SCp to gdth_cmndinfo, stage 2 - Boaz
These two move me much closer to the agenda I had in all this,
which is: "gdth diss-abuse of of scsi_cmnd IO members".
With these patches I also conform to Matthew's second patch:
"gdth: Stop abusing ->done for internal commands"
[16/16] gdth: !use_sg cleanup and use of scsi accessors
And finally this one.
Boaz
