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.

The v9fs file operations were missing the splice_read operations, which breaks sendfile() of files on such a filesystem. I discovered this while trying to load an eBPF program using iproute2 inside a 'virtme' environment which uses 9pfs for the virtual file system. iproute2 relies on sendfile() with an AF_ALG socket to hash files, which was erroring out in the virtual environment. Since generic_file_splice_read() seems to just implement splice_read in terms of the read_iter operation, I simply added the generic implementation to the file operations, which fixed the error I was seeing. A quick grep indicates that this is what most other file systems do as well.
