Generate FS_PRE_ACCESS event before truncate, without sb_writers held. Move the security hooks also before sb_start_write() to conform with other security hooks (e.g. in write, fallocate). The event will have a range info of the page surrounding the new size to provide an opportunity to fill the conetnt at the end of file before truncating to non-page aligned size.

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.
