From 8127d82705998568b52ac724e28e00941538083d Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 15 Feb 2019 16:08:25 -0500 Subject: NFS: Don't recoalesce on error in nfs_pageio_complete_mirror() If the I/O completion failed with a fatal error, then we should just exit nfs_pageio_complete_mirror() rather than try to recoalesce.
