From 4cdc685c7d06f659ef6c336d4242005cdd8df401 Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Mon, 31 Oct 2011 14:45:06 -0700 Subject: pnfs-obj: Remove redundant EOF from objlayout_io_state The EOF calculation was done on .read_pagelist(), cached in objlayout_io_state->eof, and set in objlayout_read_done() into nfs_read_data->res.eof. So set it directly into nfs_read_data->res.eof and avoid the extra member.
