From 998baad903091e43ba565bd64c82fc98ba678b68 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Fri, 28 Dec 2018 00:31:25 -0800 Subject: [PATCH] scripts/decode_stacktrace: only strip base path when a prefix of the path [ 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.
