The calling convention for nfs4_client_to_reclaim() is clumsy in that the caller needs to free memory if the function fails. It is much cleaner if the function frees its own memory. This patch changes nfs4_client_to_reclaim() to re-allocate the .data fields to be stored in the newly allocated struct nfs4_client_reclaim, and to free everything on failure. __cld_pipe_inprogress_downcall() needs to allocate the data anyway to copy it from user-space, so now that data is allocated twice. I think that is a small price to pay for a cleaner interface.

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 reStructuredText 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.
