Linus Torvalds e572410e47 ptrace: Stop supporting SIGKILL for PTRACE_EVENT_EXIT
Recently I had a conversation where it was pointed out to me that
 SIGKILL sent to a tracee stropped in PTRACE_EVENT_EXIT is quite
 difficult for a tracer to handle.
 
 Keeping SIGKILL working after the process has been killed is pain
 from an implementation point of view.
 
 So since the debuggers don't want this behavior let's see if we can
 remove this wart for the userspace API
 
 If a regression is detected it should only need to be the last change
 that is the reverted.  The other two are just general cleanups that
 make the last patch simpler.

       signal: Ensure SIGNAL_GROUP_EXIT gets set in do_group_exit
       signal: Guarantee that SIGNAL_GROUP_EXIT is set on process exit
       signal: Drop signals received after a fatal signal has been processed

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.
