Rename mmu_need_write_protect() to mmu_try_to_unsync_pages() and update a variety of related, stale comments. Add several new comments to call out subtle details, e.g. that upper-level shadow pages are write-tracked, and that can_unsync is false iff KVM is in the process of synchronizing pages. No functional change intended. Signed-off-by: Sean Christopherson <seanjc@google.com> Message-Id: <20210622175739.3610207-14-seanjc@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
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 Restructured Text 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.
