Huan Yang 8e86e9909a udmabuf: udmabuf_create pin folio codestyle cleanup
[ Upstream commit 164fd9efd4 ]

This patch aim to simplify the memfd folio pin during the udmabuf
create. No functional changes.

This patch create a udmabuf_pin_folios function, in this, do the memfd
pin folio and then record each pinned folio, offset.

This patch simplify the pinned folio record, iter by each pinned folio,
and then record each offset in it.

Compare to iter by pgcnt, more readable.

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.
