Linus recently pointed out though that if we add accessors for the atime and mtime, then that would allow us to seamlessly change how these timestamps are stored in the inode. Add new accessor functions for the atime and mtime that mirror the accessors for the ctime.

Move i_blocks up above the i_lock, which moves the new 4 byte hole to just after the timestamps, without changing the size of the structure.
