137 // size for the call to xmalloc. You can use the following feature to have

145 // USE_PROCFS at the same time... NOTE: If you enable this feature, you
146 // _must_ have patched the kernel to include the devps patch that is included
147 // in the busybox/kernel-patches directory. You will also need to create some
148 // device special files in /dev on your embedded system:
