PIDs and TIDs are already contained within the thread struct, so to avoid inconsistencies drop the extra members on the etm queue and only use the thread struct. At the same time stop using the 'unknown' thread. In a later commit we will be making samples from multiple machines so it will be better to use the idle thread of each machine rather than overlapping unknown threads. Using the idle thread is also better because kernel addresses with a previously unknown thread will now be assigned to a real kernel thread. Committer notes: Resolved conflicts with: perf addr_location: Add init/exit/copy functions perf thread: Add accessor functions for thread perf thread: Remove notion of dead threads That were present in tmp.perf-tools.next only.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
