Subject: [PATCH 3.16 161/357] nfs: rename members of nfs_pgio_data
3.16-stable review patch. If anyone has any objections, please let me know.

From: Weston Andros Adamson <dros@...marydata.com>
commit 823b0c9d9800e712374cda89ac3565bd29f6701b upstream.
Rename "verf" to "writeverf" and "pages" to "page_array" to prepare for
merge of nfs_pgio_data and nfs_pgio_header.
