We've been using a prior version of this patch in production for a few months now on single and mirrored data disks, no problems. We've done very basic testing on RAIDZ, RAIDZ2 & RAIDZ3 no problems with the version we had, but this version includes a number of important fixes for RAIDZ contributed by the zfsonlinux guys. We applied the patch to a 8.3-RELEASE based install with additional patches including patches to provide TRIM support for CAM da devices via SATA pass-through including full support for security and identify commands in camcontrol. If anyone would like those as we can provide.
