    Subject[RFC PATCH for 4.15 00/14] Restartable sequences and CPU op vector v10
    Date
    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.

    Thanks,

    Mathieu
