The code removed is from nfs_local_write_done().
That is called only in nfs_local_call_write() and nfs_local_pgio_release
is called shortly afterwards. That calls nfs_local_hdr_release() which
calls ->rpc_call_done which will be nfs_pgio_result (or something that
eventually calls nfs_pgio_result via some other ->rpc_call_done)
nfs_pgio_result calls ->rw_done which will be nfs_writeback_done which,
as you say, already contains that code.
So it looks good.
