Hello, I would like to attend LSF/MM 2015. While I am very much interested in general mm performance topics, I would particularly like to discuss: (1) Where we are at with the mmap_sem issues and progress. This topic constantly comes up each year [1,2,3] without much changing. While the issues are very clear (both long hold times, specially in fs paths and coarse lock granularity) it would be good to detail exactly *where* these problems are and what are some of the show stoppers. In addition, present overall progress and benchmark numbers on fine graining via range locking (I am currently working on this as a follow on to recent i_mmap locking patches) and experimental work, such as speculative page fault patches[4]. If nothing else, this session can/should produce a list of tangible todo items. (2) Expanding our mm performance testing. I am working on incorporating multiple VM-intensive benchmarks taken from system research papers into mmtests. Academics tend to choose their benchmarking material carefully and there's no reason we cannot learn from that. The downside is that their tools are painfully complex to use, and thus not very popular in the kernel community. Two examples are popular suites such as mosbench and PARSEC. The idea would be to present easy to use, higher level benchmarks to expose in-memory scalability issues that be useful to kernel hackers. Additionally, possibly discuss other tools folks use that can be beneficial to our internal automation.
