As I known nothing about kernel coding, could someone recommend a patch for this? It seems to be related to debugging, so as I want to test it to use for production (want to test it against ZFS, instead of L2ARC), I can leave without debugging for now.
Unfortunately I can't upgrade the kernel at this point, since it's a production server... :(
I'm seeing this error:
It seems REQ_OP_MASK was added in kernel 4.10.
