Subject: [Ocfs2-devel] [PATCH 7/9] ocfs2/dlm: Hold off sending lockres drop ref message while lockres is migrating
Date: Tue, 16 Dec 2008 15:49:21 -0800 [thread overview]
Message-ID: <1229471363-15887-8-git-send-email-sunil.mushran@oracle.com> (raw)
In-Reply-To: <1229471363-15887-1-git-send-email-sunil.mushran@oracle.com>
During lockres purge, o2dlm sends a drop reference message to the lockres
master. This patch delays the message if the lockres is being migrated.
Fixes oss bugzilla#1012
