Hi Matthew,
I have a few comments and a question on this patch, please.
(Yes, I know it won't be merged.)
Most of these are general patch process comments.
However, the last comment is the important one.
1. I had problems applying it. What tree is it against?
Say so in the description.
2. use diff -p (in SubmittingPatches)
3. use diffstat
4. Why 2 diffs against include/linux/libata.h ?
I was hoping that diffstat would show this, but it just merges
the 2 libata.h patches together. 'lsdiff' does show this,
however.
5. #includes in alpha order as much as possible.
6. Patch had some trailing whitespace (usually tabs).
Some tools detect this and warn about it.
7. Most important: What good does the ACPI interface do/add?
What I mean is that acpi_get_child() in scsi_acpi_find_channel()
always returns a handle value of 0, so it doesn't get us
any closer to determining the ACPI address (_ADR) of the SATA
devices. The acpi_get_devices() technique in my patch (basically
walking the ACPI namespace, looking at all "devices") is the
only way that I know of doing this, but I would certainly
like to find a better way.
