Sorry for not investigating myself, ENOTIME. They will unfortunately conflict with this series, yes. My journey was: 1. There's a problem with the MDB 2. I need tracepoints to figure this out 3. Having a light down here is pretty nice, I should upstream this 4. Find/understand/fix (1) 5. (4) probably should go into net In hindsight, I should probably have anticipated this situation and done away with (5) before proceeding with (3). My idea now is to get the fix accepted, wait for the next merge of net back to net-next, then fixup this series so that it does not reintroduce the MDB sync issue. I already have a version of the fix that applies on top of this series, so I'll just work it in to the switchdev refactor steps in the next version.
