[PATCH] D94844: [VFS] Add support to RedirectingFileSystem for mapping a virtual directory to one in the external FS.

[Duncan P. N. Exon Smith via Phabricator via cfe-commits]

dexonsmith added a comment.

> This patch also refactors OverlayFileSystem's directory iterator implementation (OverlayFSDirIterImpl) and VFSFromYamlDirIterImpl into a single implementation, addressing a FIXME about their conceptual similarity.

Can the `OverlayFSDirIterImpl` part be split into a separate prep commit (possibly even NFC) in order to clarify the functional changes here?
