Many thanks

There is a config option in the "kernel hacking" section of the kernels config ...


Use 4kb for kernel stacks instead of 8kb

CONFIG_4KSTACKS

Code:

Use 4Kb for kernel stacks instead of 8Kb 4KSTACKS

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. This option
will also use IRQ stacks to compensate for the reduced stackspace.


not sure if thats what your looking for, no clue about any sysctrl or other method of changing it on the fly.
