Thanks for taking the time to look into this. But the first approach was used on Friday (and is adequate considering we're starting with the bio's bi_sector). The new commit id is 1c5a63b138638d08f4dc65ed48d3d5d3bad1b08b. The moral of the story is: don't make a mistake on Thursday because that last linux-next of the week will plague you for the next 5 days. I was hoping for relief with Monday's linux-next build but alas... ;) -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
