  "message": "scsi: add free_request callback\n\nMost device models have a simple lifecycle for the hba_private field\nand they can free it when a request is completed or cancelled.\nHowever, in some cases it may be simpler to tie the lifetime\nof hba_private to that of the included SCSIRequest.  This patch\nadds a free_request callback to SCSIBusInfo that lets an HBA\ndevice model do exactly that.\n\nNormally, device models use req-\u003ehba_private \u003d\u003d NULL to flag requests\nthat have been completed already.  Device models that use free_request\nwill still need to track this using a flag.  This is the reason why\n\"converting\" existing HBAs to use free_request adds complexity and\nmakes little sense.  It is simply an additional convenience that is\nprovided by the SCSI layer.  USB-attached storage will be the first\nuser.\n\nSigned-off-by: Paolo Bonzini \u003cpbonzini@redhat.com\u003e\nSigned-off-by: Gerd Hoffmann \u003ckraxel@redhat.com\u003e\n",
