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
