modutils/*: rewrite by Timo Teras <timo.teras AT iki.fi>
- a lot faster (linear algorithmic complexity, smaller memory foot print) - a lot smaller (the old code was overly complicated) - loading of aliases is now module-init-tools compliant - blacklisting is done correctly (-b option added) - module argument quoting done right - depmod now correctly generates modules.symbols and modules.alias add/remove: 16/21 grow/shrink: 4/6 up/down: 6930/-9316 Total: -2386 bytes text data bss dec hex filename 806039 592 6680 813311 c68ff busybox_old 803498 592 6676 810766 c5f0e busybox_unstripped
