[PATCH] scripts/decode_stacktrace.sh: canonicalize basepath and modpath

Show all headers | View raw

I use decode_stacktrace.sh as

$ ./scripts/decode_stacktrace.sh vmlinux . .

It means basepath is equal to "." and decode_stacktrace stips dot from
the filepath instead of actual basepath. Not very helpful.

Let's fix this.

Canonicalize modepath too while I'm there.
