Hi Trond,
We noticed the below kernel crash on
git://git.linux-nfs.org/projects/trondmy/linux-nfs.git testing
commit 6ae373394c4257bad562817aa60464ff7fe8f9c4 ("NFSv4.1: Ask for no delegation on OPEN if using O_DIRECT")
testbox/testcase/testparams: vm-vp-quantal-x86_64/boot/1
0e3b137fbf0f4ab9 6ae373394c4257bad562817aa6
---------------- --------------------------
fail:runs %reproduction fail:runs
| | |
:100 4% 2:46 dmesg.BUG:kernel_test_crashed
The last dmesg lines before the kernel crash are
[ 0.274266] NET: Registered protocol family 1
[ 0.275236] RPC: Registered named UNIX socket transport module.
[ 0.276123] RPC: Registered udp transport module.
[ 0.276860] RPC: Registered tcp transport module.
[ 0.277617] RPC: Registered tcp NFSv4.1 backchannel transport module
Thanks,

Hi Fengguang,
I'm trying to reproduce this issue, but so far no luck. Do you have
any details on the test itself that you could share with me?
Thanks
Trond

It looks like a false report, sorry! The real crash dmesg is much
longer and it ends here:
[ 14.605487] i6300esb: Unexpected close, not stopping watchdog!
Which is not relevant to the NFS change at all.
The dmesg I looked at happen to be truncated (perhaps by email server)
exactly at a NFS line, which treats me to believe it's a good bisect.
Cheers,
Fengguang
