This is a note to let you know that I've just added the patch titled
Revert "Drivers: hv: vmbus: Fix a bug in channel rescind code"
to my char-misc git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: Revert "Drivers: hv: vmbus: Fix a bug in channel rescind code"
This reverts commit 90d33f3ec519db19d785216299a4ee85ef58ec97 as it's not
the correct fix for this issue, and it causes a build warning to be
added to the kernel tree.
