The main reason is to use new wake_up helpers that will be added in the following patches. But here are a few other reasons: * if we use two different ways, we always need to call them both. This patch fixes seccomp_notify_recv where we forgot to call wake_up_poll in the error path. * If we use one primitive, we can control how many waiters are woken up for each request. Our goal is to wake up just one that will handle a request. Right now, wake_up_poll can wake up one waiter and up(&match->notif->request) can wake up one more.

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.
