Subject: [PATCH v5 01/17] xattr: Remove unnecessary NULL attribute name check
Date: Wed, 28 Sep 2016 16:57:47 +0200 [thread overview]
Message-ID: <1475074683-26971-2-git-send-email-agruenba@redhat.com> (raw)
In-Reply-To: <1475074683-26971-1-git-send-email-agruenba@redhat.com>
When NULL is passed to one of the xattr system calls as the attribute
name, copying that name from user space already fails with -EFAULT;
xattr_resolve_name is never called with a NULL attribute name.
