Hi,
I would like to be able to load symbols from a specific debuginfo directory using
'mod -S <dir>'. This works if you unpack the corresponding kernel rpm too but I'd
like to be able to save on the disk space by just using the debuginfo rpm. This
currently doesn't work because crash doesn't explicitly search for modules ending
in .ko.debug. The simple patch below adds this support. Is this a sensible change
to make or is there a better way to do this?
