Kevin Wolf 250196f19c qcow2: Reduce number of I/O requests ... If the first part of a write request is allocated, but the second isn't and it can be allocated so that the resulting area is contiguous, handle it at once. This is a common case for sequential writes. After this patch, alloc_cluster_offset() only checks if the clusters are already allocated or how many new clusters can be allocated contigouosly. The actual cluster allocation is split off into a new function do_alloc_cluster_offset().
