From def6ed7ef45ed19c3d6ca765f3bfdff1fe4c6bba Mon Sep 17 00:00:00 2001 From: Andy Adamson Date: Wed, 1 Apr 2009 09:22:26 -0400 Subject: nfs41 write sequence setup done support Separate write calls from nfs41: sequence setup/done support Implement the write rpc_call_prepare method for asynchronuos nfs rpcs, call nfs41_setup_sequence from respective rpc_call_validate_args methods. Call nfs4_sequence_done from respective rpc_call_done methods. Note that we need to pass a pointer to the nfs_server in calls data for passing on to nfs4_sequence_done.
