With page faults we can trigger readahead on the file, and then subsequent faults can find these pages and insert them into the file without emitting an fanotify event. To avoid this case, disable readahead if we have pre-content watches on the file. This way we are guaranteed to get an event for every range we attempt to access on a pre-content watched file.

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.
