[PATCH 0/4] fstests: generic test for NFS handles

[Amir Goldstein <amir73il@gmail.com>]

Eryu,

I am working on NFS export support for overlayfs [1].
Before testing with NFS client I wanted to test the file handle API,
but apparently xfstests have only tests for the XFS specific ioctl.

So I converted the stale_handle xfs/238 test to a generic test and
added some more test cases to it. 

On the bright side, if I disable the drop_caches in the test, the
test already passes on overlayfs in my test branch, but I still have
some work to do for full NFS export support.

When I am done with that, I will add some more overlay specific
exportfs tests (e.g. export handle from lower and decode after copy up).

In the mean while, running this new test on overlayfs yields:

generic/426 3s ... [not run] overlay does not support NFS export

Tested this on ext4, xfs, btrfs, tmpfs.

Thanks,
Amir.
