Linux Plumbers Conf 2013

One Line Summary

Abstract

The full dynticks capability has been merged in 3.10. The support was still minimal at this stage and had a lot of limitations. Still it was a necessary opportunity to settle the base foundations and improve iteratively from there to remove its limitations gradually. A few aspect of full dynticks have improved since then but there is still a lot to do. This talk tries to dig into the details of what we’ll work on in the future.
