+Subject: [PATCH 2/4] smack: fix cache of access labels
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Before this commit, removing the access property of
+a file, aka, the extended attribute security.SMACK64
+was not effictive until the cache had been cleaned.
+
+This patch fixes that problem.
