Accrue the following benefits: a) Deduplicate this common bit of code. b) Don't prepare rq_vec for NFSv2 and NFSv3 spliced reads, which don't use rq_vec. This is already the case for nfsd4_encode_read(). c) Eventually, converting NFSD's read path to use a bvec iterator will be simpler. In the next patch, nfsd_iter_read() will replace nfsd_readv() for all NFS versions. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
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.
