Subject: eCryptfs: increment extent_offset once per loop interation
From: Michael Halcrow <mhalcrow@xxxxxxxxxx>
The extent_offset is getting incremented twice per loop iteration through any
given page. It should only be getting incremented once. This bug should only
impact hosts with >4K page sizes.
