InfiniBand/RDMA merge plans for 2.6.36
in [Kernel]
|
From: Roland Dreier on 4 Aug 2010 19:40 Since 2.6.35 is here, it's probably a good time to talk about 2.6.36 merge plans. All the pending things that I'm aware of are listed below. Boilerplate: If something isn't already in my tree and it isn't listed below, I probably missed it or dropped it unintentionally. Please remind me. As usual, when submitting a patch: - Give a good changelog that explains what issue your patch addresses, how you address the issue, how serious the issue is, and any other information that would be useful to someone evaluating your patch now, or trying to understand it years from now. - Please make sure that you include a "Signed-off-by:" line, and put any extra junk that should not go into the final kernel log *after* the "---" line so that git tools strip it off automatically. Make the subject line be appropriate for inclusion in the kernel log as well once the leading "[PATCH ...]" stuff is stripped off. I waste a lot of time fixing patches by hand that could otherwise be spent doing something productive like watching youtube. - Run your patch through checkpatch.pl so I don't have to nag you to fix trivial issues (or spend time fixing them myself). - Check your patch over at least enough so I don't see a memory leak or deadlock as soon as I look at it. - Build your patch with sparse checking ("C=2 CF=-D__CHECK_ENDIAN__") and make sure it doesn't introduce new warnings. (A big bonus in goodwill for sending patches that fix old warnings) - Test your patch on a kernel with things like slab debugging and lockdep turned on. And while you're waiting for me to get to your patch, I sure wouldn't mind if you read and commented on someone else's patch. We currently have a big imbalance between people who are writing patches (many) and people who are reviewing patches (mostly me). None of this means you shouldn't remind me about pending patches, since I often lose track of things and drop them accidentally. I don't think it makes sense to break down what I merged by topics this time around -- there wasn't anything big that I can think of. It was really just a matter of small improvements, fixes, and cleanups all over. Here are a few topics I'm tracking that are not ready in time for the 2.6.36 window and will need to wait for 2.6.37 at least: - XRC. While I think we made significant progress here, the fact is that this is not ready to merge at the beginning of the merge window, and so we'll need to keep working on it and wait for the next merge window. I think this is just blocked on me at the moment. - IBoE. Same as XRC; we made significant progress (and I opened an iboe branch to track this), and I think we have finally gotten the user-kernel interface nailed down yet, but it's just too late. - ummunotify-as-part-of-uverbs. I'm working on this but don't have anything ready for the merge window. - AF_IB work. I have not even had a chance to think about this yet, since I haven't dug through earlier backlog items. - mlx4 SR-IOV support. See AF_IB above. Here all the patches I already have in my for-next branch: Aleksey Senin (1): IB: Rename RAW_ETY to RAW_ETHERTYPE Alexander Schmidt (3): IB/ehca: Fix bitmask handling for lock_hcalls IB/ehca: Catch failing ioremap() IB/ehca: Init irq tasklet before irq can happen Arnd Bergmann (1): IB/qib: Use generic_file_llseek Bart Van Assche (3): IB/srp: Use print_hex_dump() IB/srp: Make receive buffer handling more robust IB/srp: Export req_lim via sysfs Ben Hutchings (1): IB/ipath: Fix probe failure path Chien Tung (1): RDMA/nes: Store and print eeprom version Dan Carpenter (2): RDMA/cxgb4: Remove unneeded assignment RDMA/cxgb3: Clean up signed check of unsigned variable Dave Olson (1): IB/qib: Allow PSM to select from multiple port assignment algorithms David Rientjes (1): RDMA/cxgb4: Remove dependency on __GFP_NOFAIL Faisal Latif (1): RDMA/nes: Fix hangs on ifdown Ira Weiny (1): IB/qib: Allow writes to the diag_counters to be able to clear them Miroslaw Walukiewicz (1): RDMA/nes: Read firmware version from correct place Or Gerlitz (3): IB/iser: Make needlessly global iser_alloc_rx_descriptors() static RDMA/cxgb3: Make needlessly global iwch_l2t_send() static RDMA/nes: Fix two sparse warnings Peter Huewe (1): RDMA/nes: Convert pci_table entries to PCI_VDEVICE Ralph Campbell (5): IB/qib: Avoid variable-length array IB/qib: Turn off IB latency mode IB/qib: Set cfgctxts to number of CPUs by default IB/qib: Limit the number of packets processed per interrupt IB/qib: Fix race between qib_error_qp() and receive packet processing Roland Dreier (6): IB/umad: Remove unused-but-set variable 'already_dead' RDMA/nes: Rewrite expression to avoid undefined semantics RDMA/cxgb4: Remove unneeded NULL check RDMA/nes: Get rid of "set but not used" variables RDMA/nes: Fix showing wqm_quanta RDMA/nes: Fix misindented code Sean Hefty (1): IB/cm: Check LAP state before sending an MRA Steve Wise (6): RDMA/cxgb4: Add module option to tweak delayed ack RDMA/cxgb4: Support variable sized work requests RDMA/cxgb4: Fix race in fini path RDMA/cxgb4: Use correct control txq RDMA/cxgb4: Set/reset the EP timer inside EP lock RDMA/cxgb4: Add timeouts when waiting for FW responses -- Roland Dreier <rolandd(a)cisco.com> || For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/index.html -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Eli sent the user space patch that was the last technical debate last week. He will also send a new patch-set in day or two. This feature was under a lot of technical review from the community. Please consider including it in 2.6.36 after all. In general - none of our new features going to be included and I wish to understand the reason behind it (I hope it's not personal :-) regards Tziporet -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
