Subject: [PATCH bpf-next v4 0/5] Separate error injection table from kprobes
Date: Thu, 11 Jan 2018 09:48:54 +0900 [thread overview]
Message-ID: <151563173430.628.5070705610243278195.stgit@devbox> (raw)
Hi,
Here are the 4th version of patches to moving error injection
table from kprobes. This series changes error-injection.h
including points for ALLOW_ERROR_INJECTION macro and add
Reviewed-by from Josef Bacik (except [3/5]).
Here is the previous version:
https://patchwork.ozlabs.org/cover/858176/
Changes in v3:
- [3/5] Change error-injection.h including points to each file
which uses ALLOW_ERROR_INJECTION instead of bpf.h
- Add Reviewed-by from Josef Bacik except [3/5]
Thank you,
