A simple more generic solution is to do this
struct things_to_keep my_bits { .. };
struct things_to_keep __persistent card_info[NUM_CARDS] { }
and have insmod do
load module up open /var/run/moduledata/$modname if exists && is from this boot then && is right size read data into __persistent ELF section endif load into kernel init module
and rmmod cleanup module open /var/run/moduledata/$modname write data from __persistent segment into file - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
