The backport of ToT to 3.4 didn't work correctly, even if it compiled. I was getting OOPSes in zram data transfers on x86---never mind ARM. I am now trying a safer approach, by just applying the patch that removes the x86 dependency. I have tested that change on x86 and it works fine (perhaps a bit more sluggish? Could be subjective). I am still working on getting the ARM side properly tested. Thank you and I hope your training goes well. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
