94d6a5f734 user namespaces: document CFS behavior
Documented the currently bogus state of support for CFS user groups with
user namespaces.  In particular, all users in a user namespace should be
children of the user which created the user namespace.  This is yet to
be implemented.

Impact: documentation fix

sched-design-CFS.txt wrongly references sched_granularity_ns sysctl,

1a73ef6ac3 CFS scheduler: documentation about scheduling policies
The documentation about the CFS scheduler is scarse when it comes to
scheduling policies. This patch adds a chapter about the scheduling
policies it supports. Peter Zijlstra provided most of the information
for it in

9b8eae7248 Documentation: create new scheduler/ subdirectory
The top-level Documentation/ directory is unmanageably large, so we
should take any obvious opportunities to move stuff into subdirectories.
These sched-*.txt files seem an obvious easy case.
