It predates the git history and most probably it was never needed. It doesn't really hurt, but it looks confusing because its purpose is not clear at all. release_task(p) is called when this task has already passed exit_notify() so signal_pending(p) == T shouldn't make any difference. And even _if_ there were a subtle reason to clear TIF_SIGPENDING after exit_notify(), this clear_tsk_thread_flag() can't help anyway. If the exiting task is a group leader or if it is ptraced, release_task() will be likely called when this task has already done its last schedule() from do_task_dead().

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 reStructuredText 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.
