If anyone has any objections, please let me know. ------------------ From: "Srivatsa S. Bhat" commit 05b4877f6a4f1ba4952d1222213d262bf8c132b7 upstream. If create_basic_memory_bitmaps() fails, usermodehelpers are not re-enabled before returning. Fix this. And while at it, reword the goto labels so that they look more meaningful.
