-// InodeNew represents ext4 inode structure which can be bigger than
-// OldInodeSize. The actual size of this struct should be determined using
-// inode.ExtraInodeSize. Accessing any field here should be verified with the
-// actual size. The extra space between the end of the inode struct and end of
-// the inode record can be used to store extended attr.
-//
-// If the TimeExtra fields are in scope, the lower 2 bits of those are used
-// to extend their counter part to be 34 bits wide; the rest (upper) 30 bits
-// are used to provide nanoscond precision. Hence, these timestamps will now
-// overflow in May 2446.
