uint64_t	calls
	Read calls forwarded so far.
uint64_t	bytes

Detailed Description

Counting shim around an ra8_vsource_read_fn.

Forwards to inner and tallies calls + bytes. One instance sits at the vsource seam (counting storage commands = cache misses); the RBKC backend nests a second one under its container file to count raw compressed bytes.

Invariant

inner is non-NULL whenever the meter is registered as a reader.
