Sometimes we need to wait for a condition to be true which must be testing while holding a lock. Correspondingly the condition is made true while holding the lock and the wake up is sent under the lock. This patch provides wake and wait interfaces which can be used for this situation when the lock is a mutex or a spinlock, or any other lock for which there are foo_lock() and foo_unlock() functions.

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.
