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