Subject: [ 010/184] usermodehelper: introduce umh_complete(sub_info)

2.6.32-longterm review patch.  If anyone has any objections, please let me know.

------------------

From: Oleg Nesterov <oleg@...hat.com>

commit b3449922502f5a161ee2b5022a33aec8472fbf18 upstream

Preparation.  Add the new trivial helper, umh_complete().  Currently it
simply does complete(sub_info->complete).
