Well, my plan is that the scsi maintainers pick up patches #1, #2, #6 and #7 and I remind you once #6 (i.e. the dependency for #8) is in Linus' tree. But with your ack the two fb patches can also go in via scsi. To James and Martin: I didn't hear from you about my merge suggestion up to now. The other affected maintainers agreed so far that (assuming you're using b4) and interpreting Helge's ack as agreement that you also pick up the fb patches, you can go for b4 am -l -t -3 -P1,2,5-8 cover.1779803053.git.u.kleine-koenig@baylibre.com If you like I can also pick up these patches (then with your ack please) and send them to Linus for the next merge window. Just tell me about your preference.
