148 // size for the call to xmalloc. You can use the following feature to have
149 // them put on the stack. For some very small machines with limited stack
150 // space, this can be deadly. For most folks, this works just fine...
151 //#define BB_FEATURE_BUFFERS_GO_ON_STACK
152 // The third alternative for buffer allocation is to use BSS. This works

161 // feature, you _must_ have patched the kernel to include the devps patch that
162 // is included in the busybox/kernel-patches directory. You will also need to
