Trond Myklebust	ebed9203b6	NFS: Fix an allocation-under-spinlock bug ... sunrpc_cache_update() will always call detail->update() from inside the detail->hash_lock, so it cannot allocate memory.

Trond Myklebust	0a6566ecd3	NFSv4: Ensure nfs_dns_lookup() and nfs_dns_update() are declared static ... Fix two 'sparse' warnings in fs/nfs/dns_resolve.c Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>	2009-12-03 15:54:01 -05:00
Trond Myklebust	e571cbf1a4	NFS: Add a dns resolver for use with NFSv4 referrals and migration ... 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>	2009-08-19 18:22:15 -04:00
