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:

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,
