138 // BusyBox will, by default, malloc space for its buffers. This costs code
139 // size for the call to xmalloc. You can use the following feature to have
140 // them put on the stack. For some very small machines with limited stack
141 // space, this can be deadly. For most folks, this works just fine...
142 //#define BB_FEATURE_BUFFERS_GO_ON_STACK
144 // Turn this on to use Erik's very cool devps, and devmtab kernel drivers,
145 // thereby eliminating the need for the /proc filesystem and thereby saving
146 // lots and lots memory for more important things. NOTE: If you enable this
147 // feature, you _must_ have patched the kernel to include the devps patch that
148 // is included in the busybox/kernel-patches directory. You will also need to
149 // create some device special files in /dev on your embedded system:
150 // mknod /dev/mtab c 10 22
