Sounds very good! The RCU topics that occur to me immediately include: o How do we tell compilers about RCU's memory-ordering requirements? Follow up to http://lwn.net/Articles/586838/ and https://lwn.net/Articles/588300/. This could potentially converge before August, but the odds do not look all that favorable. Might be an interesting discussion of the interaction between the kernel and compiler, though perhaps in the Chinese sense. ;-) o What use cases are not supported well, and what should we be doing to better support them, in RCU or otherwise? Without some reasonably controversial proposals, this aspect seems unlikely to be LKS material. o Can we do a better job of automatically catching RCU usage bugs? Or, for that matter, RCU bugs! Other thoughts for topics? Thanx, Paul
