I guess I see a separation between what you are working on and what you are publishing. You used to publish a reasonable amount of subseries for others and most of this I suspect could just be based on Linus' tree. Anyway, not a big problem except when I get days like yesterday (when I saw some of the conflicts you are noting). > Basing -mm on next is never a problem (for me).

Indeed. Some of what you have seen this time is just last minute updates of other trees and bug fixes in Linus' tree. We had about 2000 (net) commits added to linux-next in the past week (800+ over the weekend). Some of this has now migrated to Linus' tree already. > That's guessing - it's a long time since I sat down and worked out exactly > what is causing this. Which is not a trivial problem. I will run my stats script and see what pops out. -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx
