(there also could be level of nesting in the list also, for e.g. list->some_field->next and so on...) then it becomes cumbersome and difficult. I am not sure whether that facility is available, but I think it is a very useful feature, if it is not there. I would like to make a patch which gives that facility in gdb. 2) I also working on arm reversible support (having vmware) that should help me finish the insn part (if not linux ABI)... but the work has been going very slow : ( will try to catch up. 3) kernel reversible debugging, is there any work going on (such as framework on sys call revocation, memory allocation revocation, etc...), just curious to know.
