(SOLVED) ZFS and SPL not working after kernel 4.13.3-1 update

I updated to the latest kernel 4.14.3-1. After reboot, my zfs partition stopped working. modprobe doesn't recognize the module and checking dmesg, I found the message:

spl: Unknown symbol vfs_write

Just to clarify, these are both spl-dkms, and spl-dkms modules.

My intuition tells me that spl and zfs have not been upgraded for this new kernel. Correct me if I'm wrong.
For now I downgraded to the older kerrnel and everything is back to normal. Is there a solution to this? Do I need an updated zfs and spl modules to make them work for the new kernel or is there a way around the vfs_write error?

Re: (SOLVED) ZFS and SPL not working after kernel 4.13.3-1 update

The ZFS/SPL Git Master Repository already has fixes for this Problem (at least according to the commits I found, didn't test it), but there hasn't been a new ZFS Release with fixes for kernel 4.14. I suspect there will be a 0.7.4 Release of ZOL soon which will fix this problem and work with 4.14. Until that happens (and the PKGBUILDs are upgraded) You'll have to use the old 4.13 Kernel or switch to zfs-dkms-git / spl-dkms-git

I tried the git version but it didn't work. Kernel complained about missing zpios module. I'll keep the old kernel for now until the upgrade. Cheers!

Thank You  seiichiro
I had the same problem:
After I upgrade kernel to 4.14 no zfs module loaded and I had errors in dmesg for spl
spl: Unknown symbol vfs_write
I did downgrade kernel to 4.13.12 and after reboot zfs works Ok.
