Linux kernel source tree
243145bc43
The check in block_page_mkwrite that is meant to determine whether an offset is within the inode size is off by one. This bug has been copied into iomap_page_mkwrite and several filesystems (ubifs, ext4, f2fs, ceph). Fix that by introducing a new page_mkwrite_check_truncate helper that checks for truncate and computes the bytes in the page up to EOF. Use the helper in iomap. NOTE from Darrick: The original patch fixed a number of filesystems, but then there were merge conflicts with the f2fs for-next tree; a subsequent re-submission of the patch had different btrfs changes with no explanation; and Christoph complained that each per-fs fix should be a separate patch. In my view that's too much risk to take on, so I decided to drop all the hunks except for iomap, since I've actually QA'd XFS.

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.
