From df3accb849607a86278a37c35e6b313635ccc48b Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 13 Feb 2019 10:39:39 -0500 Subject: NFS: Pass error information to the pgio error cleanup routine Allow the caller to pass error information when cleaning up a failed I/O request so that we can conditionally take action to cancel the request altogether if the error turned out to be fatal.
