Brian Behlendorf f81d5ef686 Add warning for zfs_vdev_elevator option removal ... Originally the zfs_vdev_elevator module option was added as a convenience so the requested elevator would be automatically set on the underlying block devices. At the time this was simple because the kernel provided an API function which did exactly this. This API was then removed in the Linux 4.12 kernel which prompted us to add compatibly code to set the elevator via a usermodehelper. While well intentioned this introduced a bug which could cause a system hang, that issue was subsequently fixed by commit 2a0d4188. In order to avoid future bugs in this area, and to simplify the code, this functionality is being deprecated. A console warning has been added to notify any existing consumers and the documentation updated accordingly. This option will remain for the lifetime of the 0.8.x series for compatibility but if planned to be phased out of master.
