In vfs code, file_start_write() is usually called after the permission hook in rw_verify_area(). vfs_dedupe_file_range_one() is an exception to this rule. In vfs_dedupe_file_range_one(), move file_start_write() to after the the rw_verify_area() checks to make them "start-write-safe". This is needed for fanotify "pre content" events.

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.
