The section refers to .txt files but they have been moved/ renamed to
.rst some time ago. The mentioned sched-rt-group is inconvenient as
people always complained about CONFIG_RT_GROUP_SCHED.
Everything that describes CFS is not wrong but the kernel the kernel
switched to the Earliest Virtual Deadline First (EEVDF) scheduler.

Instead of updating the file links below (and adding new ones), replace
them with a link to the automatically created scheduler documetation
from that folder. This also has some EEVDF bits :)
