From 115ce575cb10918514d053ef15f597a4e6ff60e9 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 20 Sep 2012 21:19:43 -0400 Subject: [PATCH] NFSv4.1: pnfs_layout_io_set_failed must clear invalid lsegs If pnfs_layout_io_test_failed() authorises a retry of the failed layoutgets, we should clear the existing layout segments so that we start afresh. Do this in pnfs_layout_io_set_failed().
