Good morning, hope the day is going well for everyone.
The patches to fix the blktap2 issues which result in orphaned
tapdisk2 processes and the transitory deadlock on guest shutdown
didn't make it into the 4.1.3 release. Updated patches to address
these problems are available at the following location:
ftp://ftp.enjellic.com/pub/xen/xen-4.1.3.blktap1.patch
ftp://ftp.enjellic.com/pub/xen/xen-4.1.3.blktap2.patch
The patches are designed to be applied in order and have been verified
to work against the 4.1.3 release.
Best wishes for a productive week.

If these patches are already in xen-unstable then they definitely should be applied
to xen-4.1-testing.hg for Xen 4.1.4.

Please can you post these patches as emails with a changelog and a
signed-off-by. You should also CC Ian Jackson since he is the one who
does the tools backports.
The changelog should be clear about the backport status. IIRC one of
these is a backport from unstable (so the changelog should say of which
commit and preserve the original S-o-b) and the other is a
reimplementation since too much has changed in unstable so there is no
plausible backport (and the changelog should mention this).
Ideally these mails would be threaded with subjects "[PATCH 1/2] ..."
and "[PATCH 2/2] ..." so that it is obvious that there is a sequence to
them. A tool such as hg email will do this for you.
http://wiki.xen.org/wiki/Submitting_Xen_Patches has some hints on how to
use it.
If nothing has changed since the previous posting it may be sufficient
to reply to that previous postings with a "ping" message and CC Ian
there.
Ian.

Thanks for the comments and suggestions.
My target audience was primarily focused on other groups, like ours,
which are rolling their own XEN implementations and who needed blktap2
functionality. I know I've spent tons of time trying to ferret out
the patches to get a solid implementation for our needs. So I wanted
to get something which would get indexed so, hopefully, people would
find this when they need it.
Based on the number of downloads I see for the kernel patches and the
toolstack fixes there seems to be a sizable audience.... :-)
I shipped off the patches just before 4.1.3 was released and copied
Ian and Keir on them but I haven't seen them show up in the
xen-4.1-testing.hg Mercurial tree. Ian/Keir do you want another round
of the patches?

Best wishes for a productive week.

Ping?
Do we need a repost here or can these go into 4.1-testing.hg ?
I see xen-4.1-testing.hg has received other backports now.

Dr. Greg: RC1 for Xen 4.1.4 is being prepared atm, so hopefully you can re-submit
these blktap2 bugfix patches for inclusion!

Yes, my apologies for being more then a bit tardy on this. I have
been consumed with getting 4.2 validated in our development
environment.
I just sent a pair of patches to the list which I refreshed against
the top of the xen-4.1.testing Mercurial repository which contain the
blktap2 patches. With both applied 4.1.x shows correct behavior with
respect to blktap2 cleanup and termination.

Let me know if anything else is required.
Once again my apologies for being tardy about getting these
re-forwarded.
Best wishes for a successful release and a productive remainder of the
week.

Great, thanks a lot! I'm sure the maintainers will comment on the new patches.
