The plan: embed struct vfsmount into struct mount, making the latter visible only to core parts of VFS. Then move fields from vfsmount to mount, eventually leaving only mnt_root/mnt_sb/mnt_flags in struct vfsmount. Filesystem code still gets pointers to struct vfsmount and remains unchanged; all such pointers go to struct vfsmount embedded into the instances of struct mount allocated by fs/namespace.c. When fs/namespace.c et.al. get a pointer to vfsmount, they turn it into pointer to mount (using container_of) and work with that. This is the first part of series; struct mount is introduced, allocation switched to using it. Signed-off-by: Al Viro --- Reading git-diff-tree failed
