Questions:- 1)Which memory address in stack contains struct super_block *s 2)how does disassembly helps in knowing which register contain the struct super_block *s 3)bt -f gives highlighted above, register dump at the end, does that help in finding this information ???
Have you *actually* spent your time on reading the AMD 64ABI [1] ? Also there is a very nice and concise document available on x86_64 assembly [2]. While trying to analyse kernel crash dump using 'crash', utility you might want to refer this page [1] and this blog [4] as well.
