[roll] Roll fuchsia [kernel] Implement KTrace::Rewind for per-CPU mode This CL implements Rewind functionality for the per-CPU KTrace implementation using the SpscBuffer::Drain method. Note that this implementation of Rewind has slightly different semantics than the existing implementation. Specifically, Rewind now stops the trace itself, removing the need to invoke KTrace::Stop before invoking Rewind. This was done for efficiency's sake - the Stop method sends a no-op IPI to every core, and Rewind can reuse that IPI to invoke Drain.

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance in one of the communication channels documented at get involved.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
