Yes - same as the existing blk-mq queue distribution.

Are you aware that drivers like ib_srp assume that interrupts 
have been spread evenly, that means assigning vector 0 to CPU 0 and vector 
1 to CPU 4?

which will make them run into a conflict with the current blk-mq
assignment.  That's exactly the point why we're trying to move things
to a core location so that everyone can use the same mapping.
