From: Marc Zyngier <marc.zyngier@xxxxxxx> [ Upstream commit 67a28de47faa83585dd644bd4c31e5a1d9346c50 ] 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.
