Currently rpc_inline_rcv_pages() uses au_rslack to estimate the size of the upper layer reply header. This is fine for auth flavors where au_verfsize == au_rslack. However, some auth flavors have more going on. krb5i for example has two more words after the verifier, and another blob following the RPC message. The calculation involving au_rslack pushes the upper layer reply header too far into the rcv_buf. au_rslack is still valuable: it's the amount of buffer space needed for the reply, and is used when allocating the reply buffer. We'll keep that. But, add a new field that can be used to properly estimate the location of the upper layer header in each RPC reply, based on the auth flavor in use.

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.
