From 9dfe52a95a60096fc12234383a19b0f436304418 Mon Sep 17 00:00:00 2001 From: Dave Wysochanski Date: Thu, 23 May 2019 16:13:48 -0400 Subject: [PATCH] SUNRPC: Move call to rpc_count_iostats before rpc_call_done For diagnostic purposes, it would be useful to have an rpc_iostats metric of RPCs completing with tk_status < 0. Unfortunately, tk_status is reset inside the rpc_call_done functions for each operation, and the call to tally the per-op metrics comes after rpc_call_done. Refactor the call to rpc_count_iostat earlier in rpc_exit_task so we can count these RPCs completing in error.
