Subject: [PATCH] sched/Documentation: Modify the knob to base_slice_ns

After committing scheduler to EEVDF, since
commit e4ec3318a17f ("sched/debug: Rename sysctl_sched_min_granularity
to sysctl_sched_base_slice") sysctl has been changed. In the documentation
its mentioned that its one of the central tunable available for feed into
the scheduler. This changes the doc as well.

Fixes: e4ec3318a17f ("sched/debug: Rename sysctl_sched_min_granularity to sysctl_sched_base_slice")

 way the previous scheduler had, and has no heuristics whatsoever.  There is
 only one central tunable (you have to switch on CONFIG_SCHED_DEBUG):

-   /sys/kernel/debug/sched/min_granularity_ns
+   /sys/kernel/debug/sched/base_slice_ns

 which can be used to tune the scheduler from "desktop" (i.e., low latencies) to
 "server" (i.e., good batching) workloads.  It defaults to a setting suitable
