Subject: [PATCH 2/3] x86emul/test: avoid race in link farm rune
Date: Thu, 16 Feb 2017 18:56:50 +0000 [thread overview]
Message-ID: <20170216185651.30110-3-wei.liu2@citrix.com> (raw)
In-Reply-To: <20170216185651.30110-1-wei.liu2@citrix.com>
Several `ln -sf` can race with each other. Provide dedicated targets
for soft-linking directories.
