Sean Christopherson 497b1dfbca KVM: guest_memfd: Rename "struct kvm_gmem" to "struct gmem_file"
Rename the "kvm_gmem" structure to "gmem_file" in anticipation of using
dedicated guest_memfd inodes instead of anonyomous inodes, at which point
the "kvm_gmem" nomenclature becomes quite misleading.  In guest_memfd,
inodes are effectively the raw underlying physical storage, and will be
used to track properties of the physical memory, while each gmem file is
effectively a single VM's view of that storage, and is used to track assets
specific to its associated VM, e.g. memslots=>gmem bindings.

Using "kvm_gmem" suggests that the per-VM/per-file structures are _the_
guest_memfd instance, which almost the exact opposite of reality.

Opportunistically rename local variables from "gmem" to "f", again to
avoid confusion once guest_memfd specific inodes come along.

No functional change intended.

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.
