[Cluster-devel] [PATCH 7/7] dlm: implement EXPORT_OP_SAFE_ASYNC_LOCK

This patch is activating the EXPORT_OP_SAFE_ASYNC_LOCK export flag to
signal lockd that both filesystems are able to handle async lock
requests. The cluster filesystems gfs2 and ocfs2 will redirect their
lock requests to DLMs plock implementation that can handle async lock
requests.
