In good_sigevent directly compute the default return value as "task_tgid(current)". This is exactly the same as "task_pid(current->group_leader)" but written more clearly. In the thread case first compute the thread's pid. Then veify that attached to that pid is a thread of the current thread group. This has the net effect of making the code a little clearer, and making it obvious that posix timers never look up a process by a the pid of a thread. 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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
