There was a possible race in vmw_update_seqno. Because of this race it was possible for last_read_seqno to go backwards. Remove this function and replace it with vmw_update_fences which now sets and returns the last_read_seqno while holding the fence lock. This serialization via the fence lock ensures that last_read_seqno is monotonic again.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
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.
