Pull userns updates from Eric Biederman: "This is the last couple of vfs bits to enable root in a user namespace to mount and manipulate a filesystem with backing store (AKA not a virtual filesystem like proc, but a filesystem where the unprivileged user controls the content). The target filesystem for this work is fuse, and Miklos should be sending you the pull request for the fuse bits this merge window. The two key patches are "evm: Don't update hmacs in user ns mounts" and "vfs: Don't allow changing the link count of an inode with an invalid uid or gid". Those close small gaps in the vfs that would be a problem if an unprivileged fuse filesystem is mounted. The rest of the changes are things that are now safe to allow a root user in a user namespace to do with a filesystem they have mounted. The most interesting development is that remount is now safe" * 'userns-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: fs: Allow CAP_SYS_ADMIN in s_user_ns to freeze and thaw filesystems capabilities: Allow privileged user in s_user_ns to set security.* xattrs fs: Allow superblock owner to access do_remount_sb() fs: Allow superblock owner to replace invalid owners of inodes vfs: Allow userns root to call mknod on owned filesystems. vfs: Don't allow changing the link count of an inode with an invalid uid or gid evm: Don't update hmacs in user ns mounts |

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
