It is not easy to actually understand the "if (!file || !vma_merge())"
code, turn it into "if (file && vma_merge())". This makes immediately
obvious that the subsequent "if (file)" is superfluous.
As Hugh Dickins pointed out, we can also factor out the ->i_writecount
corrections, and add a small comment about that.
