This patch fixes the following sparse errors in fs/btrfs/super.c in function btrfs_show_devname() fs/btrfs/super.c: error: incompatible types in comparison expression (different address spaces): fs/btrfs/super.c: struct rcu_string [noderef] <asn:4> * fs/btrfs/super.c: struct rcu_string * The error was because of the following line in function btrfs_show_devname(): if (first_dev) seq_escape(m, rcu_str_deref(first_dev->name), " \t\n\\"); Annotating the btrfs_device::name member with __rcu fixes the sparse error.

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.
