Use a function-local struct for the poll_table passed to vfs_poll(), as nothing in the vfs_poll() callchain grabs a long-term reference to the structure, i.e. its lifetime doesn't need to be tied to the irqfd. Using a local structure will also allow propagating failures out of the polling callback without further polluting kvm_kernel_irqfd. Opportunstically rename irqfd_ptable_queue_proc() to kvm_irqfd_register() to capture what it actually does.

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.
