[roll] Roll fuchsia [kernel] Move category tracking to KTrace Moves the category bitmask out of internal::KTraceState and into the KTrace singleton. Now that categories are being set in KTrace, the diagnostic logging had to be moved to KTrace as well. This CL makes two changes that should be carefully considered: 1. The category bitmask is now loaded with relaxed semantics instead of acq/rel semantics. It is my belief that this is a safe change to make because reading/writing this mask does not need to synchronize across threads, but I'd like my reviewers to verify this. 2. ReserveRaw failures due to the ring buffer being full no longer clear the category mask. This is fine because writes are still disabled in internal::KTraceState, so there should be no functional change. This change also adds tests to verify that categories are set/unset correctly.

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.
