From 99c3ac6dbe18cdab3686a830d129f8fa586846bb Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Thu, 1 Apr 2021 15:58:45 +0100 Subject: virtiofsd: Fix security.capability comparison My security fix for the security.capability remap has a silly early segfault in a simple case where there is an xattrmapping but it doesn't remap the security.capability.
