Subject: [RFC PATCH v8 0/9] Restartable sequences system call
Date: Fri, 19 Aug 2016 16:07:45 -0400 [thread overview]
Message-ID: <1471637274-13583-1-git-send-email-mathieu.desnoyers@efficios.com> (raw)
Hi,
Here is v8 of the restartable sequences system call patchset, after
taking care of feedback received from Peter Zijlstra, Andy Lutomirski,
Boqun Feng, and Dave Watson. Added PowerPC architecture support provided
by Boqun Feng. It is based on Linux kernel v4.8-rc2.
The small library provided in kernel selftests now allows to perform
either a single final commit (do_rseq()), a speculative store before the
final commit (do_rseq2()), or a speculative memcpy before the final
commit (do_rseq_memcpy()).
Feedback is welcome!
Thanks,
Mathieu
