From 81ab6e7b26b453a795d46f2616ed0e31d97f05b9 Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Thu, 31 May 2012 16:26:15 -0700 Subject: [PATCH] kmod: convert two call sites to call_usermodehelper_fns() Both kernel/sys.c && security/keys/request_key.c where inlining the exact same code as call_usermodehelper_fns(); So simply convert these sites to directly use call_usermodehelper_fns().
