Please resubmit a clean patch instead of replying to the old one. Documentation/process/submitting-patches.rst has details on the how-tos. It is not a bug fix, so it belongs to bpf-next (Documentation/bpf/bpf_devel_QA.rst). Please tag it with bpf-next. The next revision will be v2, sample commands would be: git format-patch --subject-prefix='PATCH v2 bpf-next' ... ./scripts/checkpatch.pl ... git send-email ... ^ permalink raw reply [flat|nested] 4+ messages in thread
