uint32_t	cluster
	First cluster of the subdirectory (ignored when root).

Detailed Description

Identifies the directory a lookup/scan should operate in.

Either the volume root (is_root != 0) or a subdirectory rooted at a first cluster. This is what generalises the root-only directory primitives to nested paths: the root walker already handles both the FAT12/16 fixed-root region and a FAT32 root cluster chain, and a subdirectory is simply that same cluster-chain case starting at an arbitrary cluster.
