Commit 29b59f94 authored by NeilBrown's avatar NeilBrown Committed by Trond Myklebust

NFSv4: change nfs4_do_setattr to take an open_context instead of a nfs4_state.

The open_context can always lead directly to the state, and is always easily
available, so this is a straightforward change.
Doing this makes more information available to _nfs4_do_setattr() for use
in the next patch.
