NFSd: Move default initialisers from create_client() to alloc_client()
commit 5694c93e6c4954fa9424c215f75eeb919bddad64 upstream. Aside from making it clearer what is non-trivial in create_client(), it also fixes a bug whereby we can call free_client() before idr_init() has been called. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com> [bwh: Backported to 3.2: - Adjust context - Also move initialisation of nfs4_client::cl_strhash, but not nfs4_client::cl_revoked] Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
