generic/430 started failing in 4.12-rc3, as of 7c1d1dcc24b3 "nfsd: grant
read delegations to clients holding writes".
Looks like that reintroduced the problem fixed by 16abd2a0c124 "NFSv4.2:
fix client's attribute cache management for copy_file_range": the client
needs to invalidate its cache of the destination of a copy even when it
holds a delegation.
[olga] I'm confused what client version are you testing and against what server? I haven't seen generic/430 failing while testing upstream versions against upstream server verions. What should I try (as in what client version against what server version) to reproduce the failure?
