Subject: [Qemu-devel] [PATCH 2/7] linux-user: fcntl fixes for LTP
Date: Fri, 24 Jul 2009 19:10:27 +0200 [thread overview]
Message-ID: <1248455432-12959-3-git-send-email-uli@suse.de> (raw)
In-Reply-To: <1248455432-12959-2-git-send-email-uli@suse.de>
Fixes swaps on l_pid which were pretty much of random size. Implements
F_SETLEASE, F_GETLEASE. Now passes all LTP fcntl tests.
