[ANNOUNCE] SRP: ProfitBricks publishes its SRP Initiator patches

[Sebastian Riemer <sebastian.riemer-EIkl63zCoXaH+58JC4qpiA@public.gmane.org>]

Hello everyone,

I'm very proud to announce that we finally publish our SRP initiator
patches we've been working on for quite some time now.

In the first step we publish our way of failing IO fast as we've noticed
that the way Bart Van Assche does that in his GitHub repository doesn't
match our requirements completely.

His repo: https://github.com/bvanassche/ib_srp-backport
Our repo: https://github.com/sriemer/ib_srp

We want to fail IO fast in exactly the time we configure. With our
patches this works (or please tell us why not). We provide you with full
test descriptions and related shell scripts. Everything is done with as
little dependencies as possible.

The shell scripts can also be very useful to show how to configure and
use SRP with sysfs only. This is why I've added the scst-devel mailing
list here. We want to be as close as possible to the kernel.

We want to combine efforts here and to get valuable feedback from you
all. Evaluation, testing, criticism, comments, etc more than welcome!
Hopefully, we can get a really cool solution into the mainline together!
This would make my job as the maintainer for the ProfitBricks host
kernels a lot easier! ;-)

You'll notice: We've already adapted patches from Bart and parts of his
patches. So it is only fair to publish our patches as well. :-)

It is the same as with Bart's patches: This can't be used for
production, yet. Our patches don't have the reconnect for now. Ideas how
to implement that on top are welcome. Just send your patches directly to
me! :-)

Please further notice: There is a major bug in the upstream
multipath-tools. These read sysfs files cached which leads to IO on
offline devices. We've fixed it for us and publish the fix for you as
well. :-)

Thank you so much for your help in the past and in the future as well!
Thanks for the patience and reading this!

We'll continue publishing our SRP patches relevant for the mainline.
If you want to meet me or ProfitBricks in person, we'll have a booth on
LinuxTag in Berlin/Germany. I'll have a technical talk there about SRP:
