[Vol-dev] get_symbol

Hi, I am trying to get the value of the symbol "bt_proto" using the member function get_symbol, I checked using gdb that this symbol is a part of the bluetooth kernel module. But, I get the following error message "volatility.plugins.overlays.linux.linux: Requested symbol bt_proto not found in module kernel". Any thoughts why this might be happening? Thanks!
