When you talk about changing the required kernel version, I would find it helpful if you at least mention what actual kernel features you now want to depend on - at least the more significant ones. Aside from features, I'd rather think about how old the kernel is. 2.6.32 is over 13 years old. 3.10 is very nearly 10 years old. If there is something significant that landed in 3.10 that we want to depend on, then requiring that seems perfectly reasonable. I think the oldest SLE kernel that you might care about would be 4.12 (SLE12-SP5 - nearly 6 years old). Anyone using an older SLE release values stability over new functionality and is not going to be trialling a new mdadm. Thanks, NeilBrown
