Subject: [Qemu-devel] [PATCH 02/21] Disable semaphores fallback code for OpenBSD
Date: Wed, 16 Jan 2013 10:49:04 -0600 [thread overview]
Message-ID: <1358354963-9070-3-git-send-email-mdroth@linux.vnet.ibm.com> (raw)
In-Reply-To: <1358354963-9070-1-git-send-email-mdroth@linux.vnet.ibm.com>
From: Brad Smith <brad@comstyle.com>
Disable the semaphores fallback code for OpenBSD as modern OpenBSD
releases now have sem_timedwait().
Signed-off-by: Brad Smith <brad@comstyle.com>
Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
(cherry picked from commit 927fa909d5d5cf8c07673cd16a6d3bdc81250bc0)
