ra8_err_t(*	mkdir )(void ctx, const char path)
	Create one directory leaf.
ra8_err_t(*	unlink )(void ctx, const char path)
	Remove one regular-file leaf.
ra8_err_t(*	rmdir )(void ctx, const char path)
	Remove one empty directory leaf.
ra8_err_t(*	rename )(void ctx, const char old_path, const char *new_path, bool replace)

	Query the volume capacity and available byte count.

Detailed Description

Namespace backend operations.

space may be NULL only when k_fw_fs_cap_space_query is absent. A successful stat must report a coherent node kind/existence pair, and a successful listdir must not report more than its bound.
