From mboxrd@z Thu Jan 1 00:00:00 1970 From: Alex Elder Subject: [PATCH 2/2] libceph: don't set pages or bio in ceph_osdc_alloc_request() Date: Wed, 14 Nov 2012 10:23:16 -0600 Message-ID: <50A3C574.1030807@inktank.com> References: <50A3C524.8070303@inktank.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Return-path: Received: from mail-ie0-f174.google.com ([209.85.223.174]:37325 "EHLO mail-ie0-f174.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S932909Ab2KNQXU (ORCPT ); Wed, 14 Nov 2012 11:23:20 -0500 Received: by mail-ie0-f174.google.com with SMTP id k13so861743iea.19 for ; Wed, 14 Nov 2012 08:23:20 -0800 (PST) In-Reply-To: <50A3C524.8070303@inktank.com> Sender: ceph-devel-owner@vger.kernel.org List-ID: To: "ceph-devel@vger.kernel.org" Only one of the two callers of ceph_osdc_alloc_request() provides page or bio data for its payload. And essentially all that function was doing with those arguments was assigning them to fields in the osd request structure. Simplify ceph_osdc_alloc_request() by having the caller take care of making those assignments Signed-off-by: Alex Elder --- drivers/block/rbd.c | 8 ++++++-- include/linux/ceph/osd_client.h | 4 +--- net/ceph/osd_client.c | 15 ++------------- 3 files changed, 9 insertions(+), 18 deletions(-) diff --git a/drivers/block/rbd.c b/drivers/block/rbd.c index b6b1522..bdb099c 100644 --- a/drivers/block/rbd.c +++ b/drivers/block/rbd.c @@ -1150,14 +1150,18 @@ static int rbd_do_request(struct request *rq, (unsigned long long) len, coll, coll_index); osdc = &rbd_dev->rbd_client->client->osdc; - osd_req = ceph_osdc_alloc_request(osdc, snapc, ops, - false, GFP_NOIO, pages, bio); + osd_req = ceph_osdc_alloc_request(osdc, snapc, ops, false, GFP_NOIO); if (!osd_req) { ret = -ENOMEM; goto done_pages; } osd_req->r_flags = flags; + osd_req->r_pages = pages; + if (bio) { + osd_req->r_bio = bio; + bio_get(osd_req->r_bio); + } osd_req->r_callback = rbd_cb; rbd_req->rq = rq; diff --git a/include/linux/ceph/osd_client.h b/include/linux/ceph/osd_client.h index 6ddda5b..75f56d3 100644 --- a/include/linux/ceph/osd_client.h +++ b/include/linux/ceph/osd_client.h @@ -216,9 +216,7 @@ extern struct ceph_osd_request *ceph_osdc_alloc_request(struct ceph_osd_client * struct ceph_snap_context *snapc, struct ceph_osd_req_op *ops, bool use_mempool, - gfp_t gfp_flags, - struct page **pages, - struct bio *bio); + gfp_t gfp_flags); extern void ceph_osdc_build_request(struct ceph_osd_request *req, u64 off, u64 len, diff --git a/net/ceph/osd_client.c b/net/ceph/osd_client.c index 3e82e61..5ed9c92 100644 --- a/net/ceph/osd_client.c +++ b/net/ceph/osd_client.c @@ -166,9 +166,7 @@ struct ceph_osd_request *ceph_osdc_alloc_request(struct ceph_osd_client *osdc, struct ceph_snap_context *snapc, struct ceph_osd_req_op *ops, bool use_mempool, - gfp_t gfp_flags, - struct page **pages, - struct bio *bio) + gfp_t gfp_flags) { struct ceph_osd_request *req; struct ceph_msg *msg; @@ -229,13 +227,6 @@ struct ceph_osd_request *ceph_osdc_alloc_request(struct ceph_osd_client *osdc, memset(msg->front.iov_base, 0, msg->front.iov_len); req->r_request = msg; - req->r_pages = pages; -#ifdef CONFIG_BLOCK - if (bio) { - req->r_bio = bio; - bio_get(req->r_bio); - } -#endif return req; } @@ -431,9 +422,7 @@ struct ceph_osd_request *ceph_osdc_new_request(struct ceph_osd_client *osdc, } else ops[1].op = 0; - req = ceph_osdc_alloc_request(osdc, snapc, ops, - use_mempool, - GFP_NOFS, NULL, NULL); + req = ceph_osdc_alloc_request(osdc, snapc, ops, use_mempool, GFP_NOFS); if (!req) return ERR_PTR(-ENOMEM); req->r_flags = flags; -- 1.7.9.5
