NFS problem with past 2.6.31 git tree

[Zdenek Kabelac]

Hi

I've noticed that my qemu guest is now unable to use localy exported
nfs directory.
Directory gets mounted, plain 'ls' shows filenames - but nothing else
could be done.

ls -la gives this output:
ls: cannot access patch: Input/output error
...


Both host & guest are running same kernel:
851b147e4411df6a1e7e90e2a609773c277eefd2

I've checked last few commits and tried to revert them -
and this one seems to cure my problem when reverted:

Sep 23:  8a6e5deb8a8caa810fef2c525f5dbea2cfe04a47
NFS: Get rid of the NFS_MOUNT_VER3 and NFS_MOUNT_TCP flags

I should also probably note that I'm seeing this message in my dmesg log:
svc: failed to register lockdv1 RPC service (errno 97)
