@ -92,7 +92,7 @@ other HZ detail. Thus the CFS scheduler has no notion of "timeslices" in the
way the previous scheduler had, and has no heuristics whatsoever. There is
only one central tunable (you have to switch on CONFIG_SCHED_DEBUG):
/proc/sys/kernel/sched_granularity_ns
/proc/sys/kernel/sched_min_granularity_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

If you say Y here and the compiler supports the -mkernel-backchain
option the kernel will use a smaller kernel stack size. For 31 bit
the reduced size is 4kb instead of 8kb and for 64 bit it is 8kb
instead of 16kb. This allows to run more thread on a system and
reduces the pressure on the memory management for higher order
page allocations.
