* kwolf/for-anthony: (24 commits)
ide: Add fall through annotations
block: Create proper size file for disk mirror
ahci: Add migration support
ahci: Change data types in preparation for migration
ahci: Remove unused AHCIDevice fields
hbitmap: add assertion on hbitmap_iter_init
mirror: do nothing on zero-sized disk
block/vdi: Check for bad signature
block/vdi: Improved return values from vdi_open
block/vdi: Improve debug output for signature
block: Use error code EMEDIUMTYPE for wrong format in some block drivers
block: Add special error code for wrong format
mirror: support arbitrarily-sized iterations
mirror: support more than one in-flight AIO operation
mirror: add buf-size argument to drive-mirror
mirror: switch mirror_iteration to AIO
mirror: allow customizing the granularity
block: allow customizing the granularity of the dirty bitmap
block: return count of dirty sectors, not chunks
mirror: perform COW if the cluster size is bigger than the granularity
