This patch addresses the following bugs in the current rescind handling code:
1. Fixes a race condition where we may be invoking hv_process_channel_removal()
on an already freed channel.
2. Prevents indefinite wait when rescinding sub-channels by correctly setting
the probe_complete state.
I would like to thank Dexuan for patiently reviewing earlier versions of this
patch and identifying many of the issues fixed here.
Greg, please apply this to 4.14-final.

These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
