Hi,
There are just two clean-up patches for BPF_LOG_KERNEL log level:
patch #1 fixes the possible extra newline for bpf_log() and removes
the unnecessary calculation and truncation, and patch #2 disallows
BPF_LOG_KERNEL log level for bpf_btf_load().
Comments are welcome.
Regards,
Tao
Change Log:
v3:

* address comments from Daniel Borkmann:
patch #1: add prefix "BPF: " instead of "BPF:" for error message
patch #2: remove uncessary parenthesis, keep the max buffer length
setting of btf verifier, and add Fixes tag.
