4.4-stable review patch. If anyone has any objections, please let me know.
------------------
[ 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.
