I made the following changes: * directory scannig is done just once * if we find module to modprobe during dirscan, we immediately try to load it. If it succeeds, we exit. This makes modprobe MUCH faster in some quite coomon cases. * otherwise, we remember all module pathnames, so that we do not need to scan directory again. * If module was found but failed to load, we read ONLY that module's body, determine deps, scan in-memory list of modules, and try to load deps (recursively doing the same "read body, find deps" for each of them). * ONLY if module was not found by name, we read ALL module bodies and find alias names. Very time consuming. Still, as soon as alias is found, the module body reading stops (cuts time down by 50% on average). Then we try to load found module as above. I decided to get the above logic working correctly so that modprobe wouldn't scan whole module directory, and read each and every module in it on every call; and turn my attention to shrinking it later. -- vda _______________________________________________ busybox mailing list [email protected] http://busybox.net/cgi-bin/mailman/listinfo/busybox
