With de_thread now calling exchange_tids has_group_leader_pid no longer
makes any sense and is equivalent to calling thread_group_leader.
As there are only 2 remaining users of has_group_leader_pid let's
update the code and get rid of has_group_leader_pid.
There is one extra patch to lookup_task that performs that unifies
to code paths that become identical when has_group_leader_pid went
away.
Eric W. Biederman (4):
posix-cpu-timer: Tidy up group_leader logic in lookup_task
posix-cpu-timer: Unify the now redundant code in lookup_task
exec: Remove BUG_ON(has_group_leader_pid)
signal: Remove has_group_leader_pid

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.
