From 0b7d74eb80d06be3b5792cbdd2c77d1ccb05cc4b Mon Sep 17 00:00:00 2001 From: Yanchuan Nian Date: Fri, 4 Jan 2013 20:19:49 +0800 Subject: [PATCH] pnfs: Increase the refcount when LAYOUTGET fails the first time commit 39e88fcfb1d5c6c4b1ff76ca2ab76cf449b850e8 upstream. The layout will be set unusable if LAYOUTGET fails. Is it reasonable to increase the refcount iff LAYOUTGET fails the first time?
