Ezequiel Garcia 9db3bbf58b media: v4l2-mem2mem: Fix missing v4l2_m2m_try_run call Commit `34dbb848d5` ("media: mem2mem: Remove excessive try_run call") removed a redundant call to v4l2_m2m_try_run but instead introduced a bug. Consider the following case: 1) Context A schedules, queues and runs job A. 2) While the m2m device is running, context B schedules and queues job B. Job B cannot run, because it has to wait for job A. 3) Job A completes, calls v4l2_m2m_job_finish, and tries to queue a job for context A, but since the context is empty it won't do anything. In this scenario, queued job B will never run. Fix this by calling v4l2_m2m_try_run from v4l2_m2m_try_schedule. While here, add more documentation to these functions.

README

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.
