    Description

      This ticket is for collection of changes in lustre required for linux 4.15.

      The first issue seen is the disappearance of the kernel API setup_timer().  It has been replaced by the new timer_setup() call in linux 4.15.   Leads to build fails in all our code using setup_timer().

            Wow. Setting up my Ubuntu 18 test system I discovered zfs is installed by default.

            So I have taken a look at the timer changes for 4.15+ kernels and the patch will need to be rebased after the patches land from master-next. Several patches landed and will land soon that collide with this patch. I have a local port and will start testing now that I have Ubuntu18 setup.
