conversion. This patchset contains the following 9 patches.

0001-kernfs-invoke-dir_ops-while-holding-active-ref-of-th.patch
0002-kernfs-rename-kernfs_dir_ops-to-kernfs_syscall_ops.patch
0003-kernfs-implement-kernfs_syscall_ops-remount_fs-and-s.patch
0004-kernfs-add-missing-kernfs_active-checks-in-directory.patch
0005-kernfs-allow-nodes-to-be-created-in-the-deactivated-.patch
0006-kernfs-implement-kernfs_ops-atomic_write_len.patch
0007-kernfs-add-kernfs_open_file-priv.patch
0008-kernfs-implement-kernfs_node_from_dentry-kernfs_root.patch
0009-kernfs-implement-kernfs_get_parent-kernfs_name-path-.patch

0001-0003 update kernfs_dir_ops for active ref protection, add
additional syscall operations and rename the struct to
kernfs_syscall_ops.

0004-0005 implement an option to create new kernfs_nodes in
deactivated state so that multiple nodes can be made visible
atomically or removed without ever being visible to userland.

0006 implements kernfs_ops->atomic_write_len which will be used to
support cgroup cftype->max_write_len.

0007 adds kernfs_open_file->priv.

0008-0009 add various helpers and accessors.

This patchset is on top of
