folio_is_secretmem() is currently only used during GUP-fast. Nowadays, folio_fast_pin_allowed() performs similar checks during GUP-fast and contains a lot of careful handling -- READ_ONCE() -- , sanity checks -- lockdep_assert_irqs_disabled() -- and helpful comments on how this handling is safe and correct. So let's merge folio_is_secretmem() into folio_fast_pin_allowed(). Rename folio_fast_pin_allowed() to gup_fast_folio_allowed(), to better match the new semantics.

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.
