Date: Mon, 21 Jul 2008 22:19:34 -0700 From: Greg Kroah-Hartman <gregkh@...e.de> To: linux-kernel@...r.kernel.org Cc: Wang Chen <wangchen@...fujitsu.com>, Kay Sievers <kay.sievers@...e.de>, Greg Kroah-Hartman <gregkh@...e.de> Subject: [PATCH 70/79] kobject: Transmit return value of call_usermodehelper() to caller From: Wang Chen <wangchen@...fujitsu.com> kobject_uevent_env() drops the return value of call_usermodehelper(). It will make upper caller, such as dm_send_uevents(), to lose error information. BTW, Previously kobject_uevent_env() transmitted return of call_usermodehelper() to callers, but commit 5f123fbd80f4f788554636f02bf73e40f914e0d6 "[PATCH] merge kobject_uevent and kobject_hotplug" removed it.
