(Nearly) full tickless operation in 3.10
when you have a raid setup, especially a raid5/6 setup, you very seldom have drives spinning down.
Also, if you don't read the entire stripe, how do you check the parity information? or do you not do that level of validation ond only look at the parity information if you get a read failure?

We're only checking parity if we have to rebuild a block. The rebuilds only happen if the crc check fails, or if you get an IO error.
