Revert a fix for 4.4

Hi Linus,

The previous pull request had a split fix for NVMe, however there are corner cases where that ends up blowing up. So let's revert it for 4.4. The regression isn't introduced in this cycle, and it's "just" a performance regression, not a stability/integrity issue.

Please pull to get this single revert, thanks.
