linux-toradex.git/fs/nfs/cache_lib.h, branch v3.4.16 Linux kernel for Apalis and Colibri modules NFS: DNS resolver PipeFS notifier introduced 2012-01-31T23:20:26+00:00 Stanislav Kinsbursky skinsbursky@parallels.com 2011-11-25T14:13:12+00:00 9df69c81b469780b64f9b26bb87c048613fdeddf This patch subscribes DNS resolver caches to RPC pipefs notifications. Notifier is registering on NFS module load. This notifier callback is responsible for creation/destruction of PipeFS DNS resolver cache directory. Note that no locking required in notifier callback because PipeFS superblock pointer is passed as an argument from it's creation or destruction routine and thus we can be sure about it's validity.

NFS: split cache creation and PipeFS registration 2012-01-31T23:20:26+00:00 Stanislav Kinsbursky skinsbursky@parallels.com 2011-11-25T14:12:48+00:00 9222b955065dbb047b8db9eb2431979bff3ce700 This precursor patch splits NFS cache creation and PipeFS registartion. It's required for latter split of NFS DNS resolver cache creation per network namespace context and PipeFS registration/unregistration on MOUNT/UMOUNT events.

NFS: Add a dns resolver for use with NFSv4 referrals and migration 2009-08-19T22:22:15+00:00 Trond Myklebust Trond.Myklebust@netapp.com 2009-08-19T22:12:27+00:00 e571cbf1a4f8d8b6cfd4898df718dae84c75a8e1 The NFSv4 and NFSv4.1 protocols both allow for the redirection of a client from one server to another in order to support filesystem migration and replication. For full protocol support, we need to add the ability to convert a DNS host name into an IP address that we can feed to the RPC client. We'll reuse the sunrpc cache, now that it has been converted to work with rpc_pipefs. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
