> Our plan is to drop dependency on LLVM 4.0.1 (with custom patches) and instead compile with unpatched (either system or vanilla) LLVM 6.0. Work to transition our compiler stack to LLVM 6 is expected to complete in late Q3. Additionally, we are refactoring our packaging, so instead of a single neo package with multiple components we will have multiple versioned packages with clear dependencies.

Yes, once you follow through with the plan, there should be no issues
about merging patches to support the driver.

You may want to squeeze your timeline to be complete before 4.19-rc5,
which is the feature cutoff date for 4.20, but that is rather an
ambitious goal. Your original schedule would land the patches before
4.20-rc5 resulting in inclusion to 4.21.

PS. I'm going on a vacation for a couple of weeks.
