Bug 1680020

+++ This bug was initially created as a clone of Bug #1678726 +++

Description of problem:

The 'struct md_cache' in md-cache.c uses int data types which are not in common with the data types used in the 'struct iatt' in iatt.h . If one take a closer look to the implementations one can see that the struct in md-cache.c uses still the int data types like in the struct 'old_iatt' . This can lead to unexpected side effects and some values of iatt maybe will not mapped correctly. I would suggest to open a bug report. What do you think?

Additional info:
