7c9c1bb616 modprobe-small: trivial SEGV fix 2008-09-14 20:33:03 +00:00
Denis Vlasenko
ba1315d0fb 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

084266ed52 fix several problems with config parser:
a bug where it underflows the string
 a bug where it never frees parser_t struct
make read_config() return 0 if parser is NULL,
 make config_close() accept and ignore NULL parser -
 eliminates many if() blocks
reverse the sense of parser bit flags - negative flags
 are harder to grok.
hexdump: revert the change to use config parser, it is BIGGER
 and also requires additional quirks in parser
*: explicitly use PARSER_NORMAL instead of 0

6075b2aee0 - add FIXME. Perhaps somebody is interrested in looking into this one.
We would try to be clever and compare the *data instead of the *elt.

Somethink like this might be of more general use:
/* Unlink arbitrary element from the list that contains data */
void llist_unlink_data(llist_t **head, void *data)
{
    llist_t *elt;

    for (elt = *head; elt; elt = elt->link) {
        if (elt->data == data) {
            llist_unlink(elt);
            return;
        }
    }
