Here is an updated rseq patchset taking into account the feedback received at kernel summit and afterwards. Use-cases explanation and benchmarks can be found in patch 01 "Restartable sequences system call". This is still submitted as RFC. I'm keeping a linux-rseq tree with this patchset at: https://git.kernel.org/pub/scm/linux/kernel/git/rseq/linux-rseq.git/tag/?h=v4.14-rc8-rseq-20171106.1 If everyone is happy with it, I plan to submit this officially when the merge window opens.
