  "message": "qcow2: remove n_start and n_end of qcow2_alloc_cluster_offset()\n\nn_start can be actually calculated from offset. The number of\nsectors to be allocated(n_end - n_start) can be passed in in\nnum. By removing n_start and n_end, we can save two parameters.\n\nThe side effect is there is a bug in qcow2.c:preallocate() that\npasses incorrect n_start to qcow2_alloc_cluster_offset() is\nfixed. The bug can be triggerred by a larger cluster size than\nthe default value(65536), for example:\n\n./qemu-img create -f qcow2 \\\n  -o \u0027cluster_size\u003d131072,preallocation\u003dmetadata\u0027 file.img 4G\n\nSigned-off-by: Hu Tao \u003chutao@cn.fujitsu.com\u003e\nReviewed-by: Max Reitz \u003cmreitz@redhat.com\u003e\nReviewed-by: Benoit Canet \u003cbenoit@irqsave.net\u003e\nSigned-off-by: Kevin Wolf \u003ckwolf@redhat.com\u003e\n",
