From 3384f3df5ed939a25135e1b2734fb7cdee1720a8 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Fri, 8 Sep 2006 11:38:29 -0700 Subject: ocfs2: Allow binary names in the DLM The OCFS2 DLM uses strlen() to determine lock name length, which excludes the possibility of putting binary values in the name string. Fix this by requiring that string length be passed in as a parameter.
