Subject: [PATCH bpf-next v5 0/5] Separate error injection table from kprobes
Date: Sat, 13 Jan 2018 02:53:33 +0900 [thread overview]
Message-ID: <151577961239.17713.16735014086815016675.stgit@devbox> (raw)
Hi,
Here are the 5th version of patches to moving error injection
table from kprobes. This version fixes a bug and update
fail-function to support multiple function error injection.
Here is the previous version:
https://patchwork.ozlabs.org/cover/858663/
Changes in v5:
- [3/5] Fix a bug that within_error_injection returns false always.
- [5/5] Update to support multiple function error injection.
Thank you,
---
