3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Henrik Rydberg <rydb...@euromail.se>
commit 014639003c77a51fc319c9fdf225e7747cb6e18d upstream.
The handling of large output bulk transfers is broken; the same user
page is read over and over again. Fixed with this patch.
