Subject: [PATCH bpf-next v2 0/2] clean-up for BPF_LOG_KERNEL log level

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:
v2:
  * rebased on bpf-next
  * patch #1: add a trailing newline if needed (suggested by Martin)
  * add patch #2
 
v1: https://www.spinics.net/lists/bpf/msg48550.html

Hou Tao (2):
  bpf: clean-up bpf_verifier_vlog() for BPF_LOG_KERNEL log level
  bpf: disallow BPF_LOG_KERNEL log level for sys(BPF_BTF_LOAD)
