It's not really a bug that needs to be fixed, but more the general
issue of referencing inode->i_?time and attr->ia_?time and passing
them around. When we change the types in the inode and iattr from
timespec to timespec64, all assigments need to be modified, and lustre
has more of those assignments than any other file system I'm aware of.
