Converting a file handle to a dentry can be done call after the inode
unlink. This means that __fh_to_dentry() requires an extra check to
verify the number of links is not 0.
The issue can be easily reproduced using xfstest generic/426, which does
something like:
name_to_handle_at(&fh)
echo 3 > /proc/sys/vm/drop_caches
unlink()
open_by_handle_at(&fh)
The call to open_by_handle_at() should fail, as the file doesn't exist
anymore.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
