Subject: usermodehelper: introduce umh_complete(sub_info)
X-Git-Tag: v3.4-rc1~109^2~13
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=b3449922502f5a161ee2b5022a33aec8472fbf18;p=~emulex%2Finfiniband.git

usermodehelper: introduce umh_complete(sub_info)

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