From: Rahul Katariya To: Bryan Schumaker , linux-nfs@vger.kernel.org Content-Type: text/plain; charset=UTF-8 Sender: linux-nfs-owner@vger.kernel.org List-ID: Thanks Bryan for reply. Cent OS 6 is using 2.6.32-71.el6.x86_64 kernel. My server is netapp filer. I have increased timeout, but still same warning messages. If I execute by using -f option, non-native 64 bit LFS locking testcases are passing, but native post-LFS locking testcases still give same warning messages ====================================== $ ./runtests -f /nfstests Starting LOCKING tests: test directory (arg: -f) Testing native post-LFS locking Creating parent/child synchronization pipes.
