Date: Tue, 2 Nov 2010 19:00:51 +0100 From: Andi Kleen <andi@...stfloor.org> To: Trond.Myklebust@...app.com, bjschuma@...app.com, torvalds@...ux-foundation.org, linux-nfs@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [regression] NFS readdir change break fully cached nfs root My NFS root test systems stopped booting with 2.6.37-rc1. It just hangs after entering user space. The NFS root setup uses a slightly fancy parameter setup to minimize network traffic: nfsroot=10.23.204.1:/home/nfsroot/edwin,nocto,acregmin=86400,acregmax=86400,acdirmin=86400,acdirmax=86400 root=/dev/nfs I bisected it down to this commit from Bryan. Unfortunately it's not trivially revertable because that conflicts with later patches. commit d1bacf9eb2fd0e7ef870acf84b9e3b157dcfa7dc Author: Bryan Schumaker <bjschuma@...app.com> Date: Fri Sep 24 14:48:42 2010 -0400 NFS: add readdir cache array -Andi -- ak@...ux.intel.com -- Speaking for myself only. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
