I get that 'int' is used instead of 'enum sk_rst_reason' to allow passing drop reasons too without casting, but that makes understanding what should be 'reason' harder. Eg. when looking at the code or when using BTF (to then install debugging probes with BPF) this is not obvious. A similar approach could be done as the one used for drop reasons: enum skb_drop_reason is used for parameters (eg. kfree_skb_reason) but other valid values (subsystem drop reasons) can be used too if casted (to u32). We could use 'enum sk_rst_reason' and cast the other values. WDYT? Thanks, Antoine
