A xenbus bug-fix commit missing on the stable/linux-4.4.y branch

[M. Vefa Bicakci]

Dear all,

I recently found out that the following commit is not on the linux-4.4.y branch, even though it is on the linux-4.7.y and linux-4.8.y branches:

=== 8< ===
commit 9a035a40f7f3f6708b79224b86c5777a3334f7ea
Author: Jan Beulich <JBeulich@suse.com>
Date:   Mon Aug 15 09:02:38 2016 -0600

    xenbus: don't look up transaction IDs for ordinary writes

    This should really only be done for XS_TRANSACTION_END messages, or
    else at least some of the xenstore-* tools don't work anymore.

    Fixes: 0beef634b8 ("xenbus: don't BUG() on user mode induced condition")

This commit is required to ensure the proper operation of xenstore-related tools.

Would it be possible to include this commit in the patches queued for the next linux-4.4.y release?

Thank you,

Vefa

tomorrow.
