Date: Wed, 21 Sep 2011 21:09:33 +0530 From: Kautuk Consul <consul.kautuk@...il.com> To: Greg Kroah-Hartman <gregkh@...e.de>, Jiri Kosina <trivial@...nel.org>, jkosina@...e.cz Cc: linux-kernel@...r.kernel.org, Kautuk Consul <consul.kautuk@...il.com> Subject: [PATCH 1/1] Trivial: devtmpfsd: Setting task running/interruptible states This trivial patch makes the following changes in devtmpfsd() : - Set the state to TASK_INTERRUPTIBLE using __set_current_state instead of set_current_state as the spin_unlock is an implicit memory barrier. - After return from schedule(), there is no need to set the current state to TASK_RUNNING as the wake_up_process() function call will do this for us.
