fanotify users do not always need to decode the file handles reported with FAN_REPORT_FID. Relax the restriction that filesystem needs to support NFS export and allow reporting file handles from filesystems that only support ecoding unique file handles. Even filesystems that do not have export_operations at all can fallback to use the default FILEID_INO32_GEN encoding, but we use the existence of export_operations as an indication that the encoded file handles will be sufficiently unique and that user will be able to compare them to filesystem objects using AT_HANDLE_FID flag to name_to_handle_at(2). For filesystems that do not support NFS export, users will have to use the AT_HANDLE_FID of name_to_handle_at(2) if they want to compare the object in path to the object fid reported in an event.

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.
