[ Upstream commit 1f214e9c3aef2d0936be971072e991d78a174d71 ]
The Smatch static checker noted that in _nfs4_proc_lookupp(), the flag
RPC_TASK_TIMEOUT is being passed as an argument to nfs4_init_sequence(),
which is clearly incorrect.
Since LOOKUPP is an idempotent operation, nfs4_init_sequence() should
not ask the server to cache the result. The RPC_TASK_TIMEOUT flag needs
to be passed down to the RPC layer.

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.
