Currently I'm trying to excite any comment from James B. after the
latest respin of my eh-timeout patchset.
In _principle_ the patchset is now clean, and everyone agrees it
should get in. But as long as James B. doesn't react here I don't
see a point in sending my other patches, as they sort of rely on
each other.

Currently I have these patchsets queued:

- eh-timeout
- per-device logging level support
- 64-bit LUN support
- Further EH improvements:
  - remove duplicate hooks
  - move eh_host_reset_handler
    to take 'struct Scsi_Host' as argument,
  etc.

I was planning to send the per-device logging level support
in the next round, as this is touching quite a lot of areas,
but it's probably the most uncontroversial.
64-bit LUN support will be sent afterwards, as this needs some
modifications to the LLDDs, some of which cannot handle
64-bit LUNs without internal modifications. And I would need
to discuss with the vendors of how to handle these issues.

But then, as even the first patchset hasn't moved forward
in the recent weeks I fail to see the point in sending the others,
as I cannot be sure if and when the first one is getting in.

If there is interest I can put these patches up to my git
repository, of course.

Cheers,

Hannes

So, as you might've seen I've posted the 64-bit LUN patchset to
linux-scsi.

You can access the patches also from my git repository at

git://git.kernel.org/pub/scm/linux/kernel/hare/scsi-devel.git branch
64bit-luns

HTH.
