In a group with flag FAN_REPORT_DIR_FID, when adding an inode mark with FAN_EVENT_ON_CHILD, events on non-directory children are reported with the fid of the parent. When adding a filesystem or mount mark or mark on a non-dir inode, we want to report events that are "possible on child" (e.g. open/close) also with fid of the parent, as if the victim inode's parent is interested in events "on child". Some events, currently only FAN_MOVE_SELF, should be reported to a sb/mount/non-dir mark with parent fid even though they are not reported to a watching parent. To get the desired behavior we set the flag FAN_EVENT_ON_CHILD on all the sb/mount/non-dir mark masks in a group with FAN_REPORT_DIR_FID.

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.
