Anatol Belski f8008191d2 block: qcow: Add support variable refcount widths ... QCOW2 v3 specifies refcount_order 0-6 with refcount_bits = 1 << refcount_order. Previously only 16-bit (order 4) was supported. Changes: - RefcountBytes trait handles byte-aligned types (8/16/32/64-bit) - Generic pack/unpack for sub-byte widths (1/2/4-bit) - Function pointers for read/write selected at open time - Internal refcount type widened from u16 to u64 Signed-off-by: Anatol Belski <anbelski@linux.microsoft.com>		2026-01-25 09:36:42 +00:00
