[Ocfs2-devel] [PATCH] ocfs2: o2net: fix connect expired

[Srinivas Eeda <srinivas.eeda@oracle.com>]

Junxiao,

can you please describe under what circumstances you saw this problem? 
My understanding is o2net_connect_expired is only queued when connection 
actually broke and ENOTCONN is the right error in that case.

Thanks,
--Srini
