Linux kernel source tree

Currently, if multiple reclaimers raced on the same position, the reclaimers which detect the race will still reclaim from the same memcg. Instead, the reclaimers which detect the race should move on to the next memcg in the hierarchy. So, in the case where multiple traversals race, jump back to the start of the mem_cgroup_iter() function to find the next memcg in the hierarchy to reclaim from.

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.
