From: Alex Elder Date: Tue, 20 Nov 2012 04:55:21 +0000 (-0600) Subject: rbd: don't assign extent info in rbd_do_request() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c561191813e232aa52022532751855ff5c9fa319;p=linux-beck.git rbd: don't assign extent info in rbd_do_request() In rbd_do_request() there's a sort of last-minute assignment of the extent offset and length and payload length for read and write operations. Move those assignments into the caller (in those spots that might initiate read or write operations) Signed-off-by: Alex Elder Reviewed-by: Josh Durgin --- diff --git a/drivers/block/rbd.c b/drivers/block/rbd.c index 619d680960b1..c6917b11800b 100644 --- a/drivers/block/rbd.c +++ b/drivers/block/rbd.c @@ -1156,13 +1156,6 @@ static int rbd_do_request(struct request *rq, osd_req->r_oid_len = strlen(osd_req->r_oid); osd_req->r_file_layout = rbd_dev->layout; /* struct */ - - if (op->op == CEPH_OSD_OP_READ || op->op == CEPH_OSD_OP_WRITE) { - op->extent.offset = ofs; - op->extent.length = len; - if (op->op == CEPH_OSD_OP_WRITE) - op->payload_len = len; - } osd_req->r_num_pages = calc_pages_for(ofs, len); osd_req->r_page_alignment = ofs & ~PAGE_MASK; @@ -1269,6 +1262,13 @@ static int rbd_req_sync_op(struct rbd_device *rbd_dev, if (IS_ERR(pages)) return PTR_ERR(pages); + if (op->op == CEPH_OSD_OP_READ || op->op == CEPH_OSD_OP_WRITE) { + op->extent.offset = ofs; + op->extent.length = inbound_size; + if (op->op == CEPH_OSD_OP_WRITE) + op->payload_len = inbound_size; + } + ret = rbd_do_request(NULL, rbd_dev, NULL, CEPH_NOSNAP, object_name, ofs, inbound_size, NULL, pages, num_pages, @@ -1332,6 +1332,9 @@ static int rbd_do_op(struct request *rq, op = rbd_create_rw_op(opcode, payload_len); if (!op) goto done; + op->extent.offset = seg_ofs; + op->extent.length = seg_len; + op->payload_len = payload_len; /* we've taken care of segment sizes earlier when we cloned the bios.
