Andrew has noticed some inconsistencies in oom_reap_task_mm. Notably - Undocumented return value. - comment "failed to reap part..." is misleading - sounds like it's referring to something which happened in the past, is in fact referring to something which might happen in the future. - fails to call trace_finish_task_reaping() in one case - code duplication. - Increases mmap_sem hold time a little by moving trace_finish_task_reaping() inside the locked region. So sue me ;) - Sharing the finish: path means that the trace event won't distinguish between the two sources of finishing. Add a short explanation for the return value and fix the rest by reorganizing the function a bit to have unified function exit paths.

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.
