Subject: [uml-devel] [PATCH 5/6] UML - stub needs to tolerate SIGWINCH
Date: Tue, 3 Jun 2008 15:02:37 -0400 [thread overview]
Message-ID: <20080603190237.GA9515@c2.user-mode-linux.org> (raw)
We lost the marking of SIGWINCH as being OK to receive during stub
execution, causing a panic should that happen.
