From mboxrd@z Thu Jan 1 00:00:00 1970 From: Wendy Cheng Date: Thu, 29 Jun 2006 14:11:51 -0400 Subject: [Cluster-devel] [RFC PATCH 1/3] NLM lock failover - lock release Message-ID: <44A417E7.5090500@redhat.com> List-Id: To: cluster-devel.redhat.com MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit The patch piggy-backs the logic into "rq_daddr" field of struct svc_rqst where NFS server ip address is stored. Upon writing IPv4 address in standard dot notation into /proc/fs/nfsd/nlm_unlock, the logic will examine NLM's global nlm_files list and subsequently unlock the associated file if server ip address matches. Due to the size of rq_daddr (u32), we would not be able to support IPV6 for this round of changes. Another to-do item is to enable client:server ip pairs to allow NFS V4 failover. -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
