[PATCH bpf-next v1 04/11] namei: expose the stepwise ancestor walk to fs/

[sashiko-bot at kernel.org]

> Make vfs_walk_start(), vfs_walk_next() and vfs_walk_end() non-static
> and declare them in fs/internal.h next to the walk state, so an
> iterating consumer (BPF) can drive the walk with every step and
> invariant staying in namei.c.  vfs_walk_ancestors() and its callback
> contract are unchanged.
