I already discussed this with Martin Schwidefsky and we decided *not* to go via stable but instead "warn" Ubuntu explicitly. AFAIK you are the only official distribution that uses 4.13 for zfcpdump - therefore IMHO this should be sufficient. > Also, i believe zfcpdump-kernel that we currently ship does have debugfs > enabled. Are you using zfcpdump-kernel as provided in ubuntu? I did not check anything - this bugzilla was just a heads-up. > But we will > note and will explicitely enable CONFIG_DEBUG_FS=y when we refress > zfcpdump-kernel with v4.13+.
