Here maybe it's possible to use offset bigger than i_size, because
i_size_read is "atomic" but something can happen between two calls,
isn't it?
We're holding the i_mutex so we are safe, i_size_read is used just for
consistency sake. Thanks,

Oh, I'm sorry, I misread the patch, ok. Maybe we can use i_size at this
point without i_size_read.
