Merge patch series "target: RW/num_cmds stats improvements"
Mike Christie <michael.christie@oracle.com> says:
The following patches were made over Linus tree. They fix/improve the
stats used in the main IO path. The first patch fixes an issue where
I made some stats u32 when they should have stayed u64. The rest of
the patches improve the handling of RW/num_cmds stats to reduce code
duplication and improve performance.
