Pull AFS updates from David Howells: "Here's a set of patches for AFS. The first three are trivial, deleting unused symbols and rolling out a wrapper function. The fourth and fifth patches make use of the previously added RCU-safe request_key facility to allow afs_permission() and afs_d_revalidate() to attempt to operate without dropping out of RCU-mode pathwalk. Under certain conditions, such as conflict with another client, we still have to drop out anyway, take a lock and consult the server" * tag 'afs-next-20190915' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: afs: Support RCU pathwalk afs: Provide an RCU-capable key lookup afs: Use afs_extract_discard() rather than iov_iter_discard() afs: remove unused variable 'afs_zero_fid' afs: remove unused variable 'afs_voltypes'
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.
