The function do_group_exit has an optimization that avoids taking siglock and doing the work to find other threads in the signal group and shutting them down. It is very desirable for SIGNAL_GROUP_EXIT to always been set whenever it is decided for the process to exit. That ensures only a single place needs to be tested, and a single bit of state needs to be looked at. This makes the optimization in do_group_exit counter productive. Make the code and maintenance simpler by removing this unnecessary option. Link: https://lkml.kernel.org/r/87letod4v3.fsf_-_@email.froward.int.ebiederm.org Signed-off-by: "Eric W.

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.
