Merge branch 'work.mount-syscalls' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull mount ABI updates from Al Viro: "The syscalls themselves, finally. That's not all there is to that stuff, but switching individual filesystems to new methods is fortunately independent from everything else, so e.g. NFS series can go through NFS tree, etc. As those conversions get done, we'll be finally able to get rid of a bunch of duplication in fs/super.c introduced in the beginning of the entire thing. I expect that to be finished in the next window..." * 'work.mount-syscalls' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: vfs: Add a sample program for the new mount API vfs: syscall: Add fspick() to select a superblock for reconfiguration vfs: syscall: Add fsmount() to create a mount for a superblock vfs: syscall: Add fsconfig() for configuring and managing a context vfs: Implement logging through fs_context vfs: syscall: Add fsopen() to prepare for superblock creation Make anon_inodes unconditional teach move_mount(2) to work with OPEN_TREE_CLONE vfs: syscall: Add move_mount(2) to move mounts around vfs: syscall: Add open_tree(2) to reference or clone a mount
