From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yann Droneaud Subject: [PATCH] IB/core: temporarily disable create_flow/destroy_flow uverbs Date: Thu, 10 Oct 2013 11:10:55 +0200 Message-ID: <1381396255-13005-1-git-send-email-ydroneaud@opteya.com> Return-path: Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Roland Dreier , Roland Dreier , Or Gerlitz Cc: Yann Droneaud , linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: linux-rdma@vger.kernel.org create_flow/destroy_flow uverbs are under review and should be considered too experimental at this point. To not expose to userspace such experimental feature, the data structure and code is temporarily disabled for v3.12. The feature will be enabled after proper cleanup for v3.13. Signed-off-by: Yann Droneaud Link: http://marc.info/?i=cover.1381351016.git.ydroneaud-RlY5vtjFyJ3QT0dZR+AlfA@public.gmane.org Link: http://marc.info/?i=cover.1381177342.git.ydroneaud-RlY5vtjFyJ3QT0dZR+AlfA@public.gmane.org --- Or, You will probably don't like this patch ... but I think they're too many reasons to not push create_flow/destroy_flow uverbs in its current form for v3.12. This patch is short, simpler so it's a good candidate for v3.12. Pushing all the other "important" ones is probably going to be badly seen by Linus.
