NeilBrown d202cce896 sunrpc: never return expired entries in sunrpc_cache_lookup ... If sunrpc_cache_lookup finds an expired entry, remove it from the cache and return a freshly created non-VALID entry instead. This ensures that we only ever get a usable entry, or an entry that will become usable once an update arrives. i.e. we will never need to repeat the lookup. This allows us to remove the 'is_expired' test from cache_check (i.e. from cache_is_valid). cache_check should never get an expired entry as 'lookup' will never return one. If it does happen - due to inconvenient timing - then just accept it as still valid, it won't be very much past it's use-by date. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J.
