If you look carefully at the diffs, the old

	struct timespec di_atime;

changed to

	int32_t		di_atime;
	int32_t		di_atimensec;

which makes it relatively clear what happened, especially if you look
at the byte offsets in the comments.  di_atime.ts_sec became di_atime,
and di_atime.ts_nsec became di_atimensec.  The diff also describes the
reason for this change:

+ * This structure defines the on-disk format of a dinode. Since
+ * this structure describes an on-disk structure, all its fields
+ * are defined by types with precise widths.
