commit 9a089b21f79b47eed240d4da7ea0d049de7c9b4d upstream. Send a FS_ERROR message via fsnotify to a userspace monitoring tool whenever a ext4 error condition is triggered. This follows the existing error conditions in ext4, so it is hooked to the ext4_error* functions.

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.
