So far, all callers of exportfs_encode_inode_fh(), except for fsnotify's show_mark_fhandle(), check that filesystem can decode file handles, but we would like to add more callers that do not require a file handle that can be decoded. Introduce a flag to explicitly request a file handle that may not to be decoded later and a wrapper exportfs_encode_fid() that sets this flag and convert show_mark_fhandle() to use the new wrapper. This will be used to allow adding fanotify support to filesystems that do not support NFS export.

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.
