I too verified that the size of the whole structure matches that of MSR  64 bits (8 bytes). 

Initially when IFS scan was added the  all MSR structure members were  bit-fields, later there was a suggestion to
use basic C types if applicable during subsequent Array BIST patch series. I followed this approach with the  current patch series . 

I will change the current series to use all bit-field MSR structures in v2, given mixing basic types and bitfields is a a source of confusion
