Anatol Belski cc96fc14b4 block: qcow: Implement dirty bit support for QCOW2 v3 images ... Add support for the dirty bit (bit 0 of incompatible_features) which indicates the image was not closed cleanly. This improves data integrity by allowing detection of potentially corrupted images. On open: - If dirty bit is already set, log a warning and trigger refcount rebuild - Set the dirty bit and write it to disk immediately - Sync to ensure persistence before any writes - Skip dirty bit and refcount rebuild for readonly files On clean close: - Clear the dirty bit in the header - Write it to disk and sync Signed-off-by: Anatol Belski <anbelski@linux.microsoft.com>		2026-01-26 11:24:35 +00:00
