Roland Dreier posted an updated overview of his InfiniBand driver merge plans during the upcoming 2.6.24-rc1 merge window. The InfiniBand driver was first merged into the 2.6.11 Linux kernel. Roland noted, "since 2.6.23 still isn't out, and I've managed to reduce my patch review backlog a bit, it's probably a good idea to give another update about what I have queued for 2.6.24 already and what I hope to get to before the merge window opens." His description of the upcoming merge queue is broken into three sections, one for each subdirectory within drivers/infiniband. In addition to listing all patches intended for 2.6.24, Roland also listed two issues that would most likely wait for 2.6.25:

"1) Multiple CQ event vector support. I haven't seen any discussions about how ULPs or userspace apps should decide which vector to use, and hence no progress has been made since we deferred this during the 2.6.23 merge window.

"2) XRC. Given the length of the backlog above and the fact that a first draft of this code has not been posted yet, I don't see any way that we could have something this major ready in time."

"With 2.6.24 probably opening in the not-too-distant future, it's probably a good time to review what my plans are for when the merge window opens," began Roland Dreier on the Linux Kernel mailing list. He reflected on the recent decision to phase in usage of reviewed-by tags noting that he was a little behind on reviews, "unfortunately, due to the length of the backlog and the fact that 2.6.23 seems fairly close, some of the things listed below are going to miss the 2.6.24 merge window." Roland continued, stressing the importance of getting in-depth reviews:

"Although the plan is to phase in requiring 'Reviewed-by:' gently, for this merge, if you can get someone other than me to review your work, then the chances of it being merged increase dramatically. I'm talking about a real review -- ideally, someone independent (from another company would be good) who is willing to provide a 'Reviewed-by:' line that means the reviewer has really looked at and thought about the patch. There should be a mailing list thread you can point me at where the reviewer comments on the patch and a new version of that patch addressing all comments is posted (or in exceptional cases, where the patch is perfect to start with, where the reviewer says the patch is great)."
