[roll] Roll fuchsia [kernel][vm] Add trace events to scanner and PMM paths Add VM trace duration events to certain hot paths in the system: - page fault and accessed fault internal functions. Can be enabled with vm_tracing_level=2. - scanner page queue rotations, lru processing and harvesting of accessed bits. Can be enabled with vm_tracing_level=2. - PMM alloc and free functions. Can be enabled with vm_tracing_level=3. These trace events should help identify kernel locks page (or accessed) faults sometimes seem to wait on for long periods during audio underflows.

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 via the IRC channel #fuchsia on Freenode.
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.
