You mean, i.e you did kmalloc() inside kernel module then later you want to know is it forgotten to be kfree()-ed? In that case, I say it's hard because AFAIK kmalloc()-ed pages isn't assigned to certain process address space. Even if it's assigned to a process address space, you still need something like valgrind to know whether something is leaked or not. Unfortunately valgrind can only do that in user space. Linux-mm folks should provide you better explanation. regards, Mulyadi -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
