This tracepoint gives visibility on how often the flushing of memcg stats occurs and contains info on whether it was forced, skipped, and the value of stats updated. It can help with understanding how readers are affected by having to perform the flush, and the effectiveness of the flush by inspecting the number of stats updated. Paired with the recently added tracepoints for tracing rstat updates, it can also help show correlation where stats exceed thresholds frequently.

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.
