| Subject: 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. |
