From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Matthew Wilcox To: v9fs-developer@lists.sourceforge.net Cc: linux-fsdevel@vger.kernel.org, Eric Van Hensbergen , Ron Minnich , Latchesar Ionkov , linux-kernel@vger.kernel.org, Matthew Wilcox Subject: [PATCH 0/6] 9p: Use IDRs more effectively Date: Thu, 28 Jun 2018 06:26:23 -0700 Message-Id: <20180628132629.3148-1-willy@infradead.org> Sender: linux-kernel-owner@vger.kernel.org List-ID: The 9p code doesn't take advantage of the IDR's ability to store a pointer. We can actually get rid of the p9_idpool abstraction and the multi-dimensional array of requests. I haven't tested these patches, so caveat maintainer. Matthew Wilcox (6): 9p: Change p9_fid_create calling convention 9p: Replace the fidlist with an IDR 9p: Embed wait_queue_head into p9_req_t 9p: Remove an unnecessary memory barrier 9p: Use a slab for allocating requests 9p: Remove p9_idpool include/net/9p/9p.h | 8 - include/net/9p/client.h | 62 ++------ net/9p/Makefile | 1 - net/9p/client.c | 322 ++++++++++++++-------------------------- net/9p/mod.c | 7 +- net/9p/trans_virtio.c | 2 +- net/9p/util.c | 141 ------------------ 7 files changed, 132 insertions(+), 411 deletions(-) delete mode 100644 net/9p/util.c -- 2.18.0
