For normal operation 14 it is not recommended because it looks ugly and doesn't cooperate 15 with klogd/syslogd or the X server. You should normally N here, 16 unless you want to debug such a crash. 17 18config 16KSTACKS 19 bool "Use 16Kb for kernel stacks instead of 8Kb" 20 help 21 If you say Y here the kernel will use a 16Kb stacksize for the 22 kernel stack attached to each process/thread. The default is 8K. 23 This increases the resident kernel footprint and will cause less 24 threads to run on the system and also increase the pressure 25 on the VM subsystem for higher order allocations. 26 27endmenu 28
