> AFAIK you are the only official distribution that uses 4.13 for zfcpdump - > therefore IMHO this should be sufficient. That is not true. We do not use v4.13 kernel for zfcpdump-kernel package. zfcpdump-kernel package is based on v4.9 and upgrading that to v4.10+ fails to perform any dumps at all.
Please see https://bugs.launchpad.net/ubuntu/+source/zfcpdump- kernel/+bug/1722735 which has been requested for reverse-proxy. Why was debugfs disabled upstream? Especially since s390-tools explicitly tries to mount debugfs. ** Changed in: ubuntu-z-systems Status: Incomplete => Confirmed ** No longer affects: linux-hwe (Ubuntu) ** No longer affects: zfcpdump-kernel (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1719290 Title: CONFIG_DEBUG_FS is not enabled by "make zfcpdump_defconfig" with Ubuntu 17.10 (kernel 4.13) Status in Ubuntu on IBM z Systems: Fix Released Status in linux package in Ubuntu: Fix Released Bug description: Ubuntu 17.10 uses kernel 4.13.
