[RESEND PATCH 2/2] scripts/decode_stacktrace: Only strip base path when a prefix of the path

From: Marc Zyngier
Date: Mon Dec 10 2018 - 12:47:29 EST


Running something like:

decodecode vmlinux .

leads to interested results where not only the leading "." gets stripped
from the displayed paths, but also anywhere in the string, displaying
something like:

kvm_vcpu_check_block (arch/arm64/kvm/virt/kvm/kvm_mainc:2141)

which doesn't help further processing.

Fix it by only stripping the base path if it is a prefix of the path.
