RQ_SPLICE_OK is a bit of a layering violation. Also, a subsequent patch is going to provide a mechanism for always disabling splice reads. Splicing is an issue only for NFS READs, so refactor nfsd_read() to check the auth type directly instead of relying on an rq_flag setting. The new helper will be added into the NFSv4 read path in a subsequent patch. Reviewed-by: Jeff Layton <jlayton@kernel.org> 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.
