+config 16KSTACKS
+ bool "Use 16Kb for kernel stacks instead of 8Kb"
+ help
+ If you say Y here the kernel will use a 16Kb stacksize for the
+ kernel stack attached to each process/thread. The default is 8K.
+ This increases the resident kernel footprint and will cause less
+ threads to run on the system and also increase the pressure
+ on the VM subsystem for higher order allocations.
