/sys/kernel/slab/cache_name is a real directory but then there are the aliases in /sys/kernel/slab/alias_name pointing to that directory that also have to be removed. So I need to scan for symlinks in /sys/kernel/slab/* pointing to /sys/kernel/slab/cache_name. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
