Hi Al,

Here's a set of patches that converts the mount_single()-using filesystems
to use the new fs_context struct.  There may be prerequisite commits in the
branch detailed below.

 (1) Add a new keying to vfs_get_super() that indicates that
     ->reconfigure() should be called instead of (*fill_super)() if the
     superblock already exists.

 (2) Convert debugfs.

 (3) Convert tracefs.

 (4) Convert pstore.

 (5) Fix a bug in hypfs.

 (6) Convert hypfs.

 (7) Convert spufs.

 (8) Kill off mount_single().

These can be found in the following branch:

	http://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git/log/?h=mount-api-viro

Thanks,
David
