Subject: [patch 5/5] sputrace : use marker_synchronize_unregister()
Date: Wed, 01 Oct 2008 12:03:29 -0400 [thread overview]
Message-ID: <20081001160425.577543958@polymtl.ca> (raw)
In-Reply-To: 20081001160324.889716972@polymtl.ca
We need a marker_synchronize_unregister() before the end of exit() to make sure
every probe callers have exited the non preemptible section and thus are not
executing the probe code anymore.
