Subject: [PATCH] SUNRPC: RPC level errors should always set task->tk_rpc_status
Date: Thu, 12 Sep 2019 08:06:51 -0400	[thread overview]
Message-ID: <20190912120651.11277-1-trond.myklebust@hammerspace.com> (raw)

Ensure that we set task->tk_rpc_status for all RPC level errors so that
the caller can distinguish between those and server reply status errors.
