- Fix some comments. - Consistently access i_size directly rather than using i_size_read(), since in all relevant cases we're under inode_lock(). - Simplify the alignment checks by using the IS_ALIGNED() macro. - In ext4_insert_range(), do the check against s_maxbytes in a way that is safe against signed overflow. (This doesn't currently matter for ext4 due to ext4's limited max file size, but this is something other filesystems have gotten wrong. We might as well do it safely.)

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.
