Subject: [uml-devel] [PATCH 10/14] uml: stub needs to tolerate SIGWINCH
Date: Fri, 1 Aug 2008 18:41:33 -0400 [thread overview]
Message-ID: <20080801224133.GA13713@c2.user-mode-linux.org> (raw)
From b4783df9f0fefe1af0b828748b8abe39ada65652 Mon Sep 17 00:00:00 2001
We lost the marking of SIGWINCH as being OK to receive during stub
execution, causing a panic should that happen.
