Subject: ocfs2/dlm: Handle EAGAIN for compatibility - v2
X-Git-Tag: v2.6.33-rc8~38^2~10

ocfs2/dlm: Handle EAGAIN for compatibility - v2

Mainline commit aad1b15310b9bcd59fa81ab8f2b1513b59553ea8 made the
dlm_begin_reco_handler() return -EAGAIN instead of EAGAIN.

As this error is transmitted over the wire, we want the receiver,
dlm_send_begin_reco_message(), to understand both the older EAGAIN and
the newer -EAGAIN, to allow rolling upgrade of the cluster nodes.
