      "message": "block: add request-\u003eraw_data_len\n\nWith padding and draining moved into it, block layer now may extend\nrequests as directed by queue parameters, so now a request has two\nsizes - the original request size and the extended size which matches\nthe size of area pointed to by bios and later by sgs.  The latter size\nis what lower layers are primarily interested in when allocating,\nfilling up DMA tables and setting up the controller.\n\nBoth padding and draining extend the data area to accomodate\ncontroller characteristics.  As any controller which speaks SCSI can\nhandle underflows, feeding larger data area is safe.\n\nSo, this patch makes the primary data length field, request-\u003edata_len,\nindicate the size of full data area and add a separate length field,\nrequest-\u003eraw_data_len, for the unmodified request size.  The latter is\nused to report to higher layer (userland) and where the original\nrequest size should be fed to the controller or device.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n"

      "message": "block: update bio according to DMA alignment padding\n\nDMA start address and transfer size alignment for PC requests are\nachieved using bio_copy_user() instead of bio_map_user().  This works\nbecause bio_copy_user() always uses full pages and block DMA alignment\nisn\u0027t allowed to go over PAGE_SIZE.\n\nHowever, the implementation didn\u0027t update the last bio of the request\nto make this padding visible to lower layers.  This patch makes\nblk_rq_map_user() extend the last bio such that it includes the\npadding area and the size of area pointed to by the request is\nproperly aligned.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n"
