Chuck Lever 7dbb53baed sunrpc: Simplify do_enqueue tracing
There are three cases where svc_xprt_do_enqueue() returns without
waking an nfsd thread:

1. There is no work to do

2. The transport is already busy

3. There are no available nfsd threads

Only 3. is truly interesting. Move the trace point so it records
that there was work to do and either an nfsd thread was awoken, or
a free one could not found.

As an additional clean up, remove a redundant comment and a couple
of dprintk call sites.

README

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.
