Subject: [PATCH] x86,xen: use current->state helpers
Date: Mon, 26 Jan 2015 02:10:08 -0800 [thread overview]
Message-ID: <1422267008.24914.10.camel@stgolabs.net> (raw)
Call __set_current_state() instead of assigning the new state directly.
These interfaces also aid CONFIG_DEBUG_ATOMIC_SLEEP environments,
keeping track of who changed the state.
