└─>Use 4Kb for kernel stacks instead of 8Kb
In linux kernel since version 2.6.12
If you say Y here the kernel will use a 4Kb stacksize for the
kernel stack attached to each process/thread. This facilitates
running more threads on a system and also reduces the pressure
on the VM subsystem for higher order allocations.
