Thanks for the update on this compat fix. I've tested this on:
upstream 5.6-rc5 lowlatency + generic upstream 5.5 lowlatency + generic ubuntu 5.4.0-18 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1866730 Title: Need patch for post 5.5 low-latency kernels Status in zfs-linux package in Ubuntu: In Progress Bug description: CONFIG_PREEMPT_RCU=y enabled post 5.4.x kernels have __rcu_read_lock exposed as GPL-ONLY, which breaks zfs compilation on kernels with that enabled. (Ubuntu low-latency kernels have that enabled IIRC.)
