In the version i'm looking at (v3.2-rc5) PLIST_NODE_INIT takes only
one argument.

You need to use it like this:

    struct plist_head head = PLIST_HEAD_INIT(head);

(it can only be used for static initializations)

Hmm. plist_add and plist_del seem to be lacking EXPORT_SYMBOL
alltogether; could you try compiling with this patch as a workaround?

Hope This Helps,
