From f094323867668d50124886ad884b665de7319537 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 26 Jan 2024 10:39:42 -0500 Subject: [PATCH] sunrpc: pass in the sv_stats struct through svc_create_pooled Since only one service actually reports the rpc stats there's not much of a reason to have a pointer to it in the svc_program struct. Adjust the svc_create_pooled function to take the sv_stats as an argument and pass the struct through there as desired instead of getting it from the svc_program->pg_stats.
