| |
Hello, Ingo,
This pull request is for an RCU change that permits waiting for grace periods started by CPUs late in the process of going offline. Lack of this capability is causing failures:
http://lkml.kernel.org/r/db9c91f6-1b17-6136-84f0-03c3c2581ab4@codeaurora.org
Although these failures predate v4.12, and thus are in some sense not regressions, it would be good for them to be fixed sooner rather than later, hence this RFC pull request.
