Provide a netfs write helper, netfs_perform_write() to buffer data to be written in the pagecache and mark the modified folios dirty. It will perform "streaming writes" for folios that aren't currently resident, if possible, storing data in partially modified folios that are marked dirty, but not uptodate. It will also tag pages as belonging to fs-specific write groups if so directed by the filesystem. This is derived from generic_perform_write(), but doesn't use ->write_begin() and ->write_end(), having that logic rolled in instead.

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.
