From 840210fc4872bcbc17ab4f435f28021dce9d0aff Mon Sep 17 00:00:00 2001 From: Weston Andros Adamson Date: Tue, 24 Jun 2014 10:59:52 -0400 Subject: [PATCH] sunrpc: add rpc_count_iostats_idx Add a call to tally stats for a task under a different statsidx than what's contained in the task structure. This is needed to properly account for pnfs reads/writes when the DS nfs version != the MDS version.
