[RFC PATCH 0/4] re-enable tests that require scratch dev on NFS

[Eryu Guan <eguan@redhat.com>]

This commit disables tests requires scratch dev running on NFS

c041421 xfstests: stop special casing nfs and udf

Now re-enable them to get a larger test coverage on NFS.

Also do more updates to avoid unnecessary failures on NFS.

I tested against NFSv3 NFSv4.0 NFSv4.1 (both linux server and client,
with 3.18-rc1 kernel), the results look good.

Failures on NFSv3:
generic/035 generic/089 generic/258 generic/294

Failures on NFSv4.0:
generic/035 generic/169 generic/294

Failures on NFSv4.1:
I hit kernel BUG_ON when testing on NFSv4.1 in generic/285
SEEK_DATA/SEEK_HOLE test. I think there's already a patch to fix it.

http://www.spinics.net/lists/linux-nfs/msg47359.html

Note that generic/294 does remount,ro on SCRATCH_DEV, but TEST_DEV is
affected too, so some tests after generic/294 fail because of EROFS.
Run the failed tests seperately and they all passed.

I'm not sure if it's a bug, but I filed one, please see
https://bugzilla.redhat.com/show_bug.cgi?id=1158046

Thanks,
Eryu
