[PATCH] docs: fix memory.low description in cgroup-v2.rst

From: Jon Haslam
Date: Wed Sep 25 2019 - 15:56:27 EST


The current cgroup-v2.rst file contains an incorrect description of when
memory is reclaimed from a cgroup that is using the 'memory.low'
mechanism. This fix simply corrects the text to reflect the actual
implementation.
