Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

->readpage looks in file->private_data to try and find out how the userspace program set "count" in read(2) or with "dd bs=" or whatever. ->readpage uses "count" and inode->i_size to calculate how much data Orangefs should deposit in the Orangefs shared buffer, and remembers which slot the data is in. After copying data from the Orangefs shared buffer slot into "the page", readpage tries to increment through the pagecache index and fill as many pages as it can from the extra data in the shared buffer. Hopefully these extra pages will soon be needed by the vfs, and they'll be in the pagecache already.

README
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.
