If we're in the error path failing links and we have a link that has grabbed a reference to the fs_struct, then we cannot safely drop our reference to the table if we already hold the completion lock. This adds a hardirq dependency to the fs_struct->lock, which it currently doesn't have. Defer the final cleanup and free of such requests to avoid adding this dependency.

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.
