- Check decode/read of file handles after rename of parent
- Check decode/read of file handles after rename of grandparent
- Check decode/read of file handles after move to new parent
- Check encode/decode/read of file handles in non-upper overlay
This test requires and enables overlayfs NFS export support and merge
dir rename support (redirect_dir).
NFS export support depends on and requires overlayfs index feature.
This test covers only encode/decode of file handles for overlayfs
configuration of all layers on the same base fs.

Multiple redirects to the same lower dir will falsely return the
same st_ino/st_dev for two different upper dirs and will cause
'diff' to falsely report that content of directories is the same
when it is not.
This test checks that overalyfs detects and fails lookup of a
multiply redirected dir.
The check for multiply redirected dir was implemented by kernel
commit titled "ovl: hash directory inodes for fsnotify".

Several tests check that index dir is empty after upper entries have
been unlinked. With nfs_export=on, index will contain a whiteout
index entry in that case so, allow chardevs when checking for clean

Mount option index=on checks on mount that upper dir is not being
reused with a different lower dir than the first lower dir it was
mounted with. This behavior is verified by test overlay/037.
In this test however, it is not desired to fail mount on mismatch of
upper/lower, so use the matching upper/lower dirs in this test.
The mismatch went unnoticed because the index=off mounts do not
verify lower dir and the index=on mounts fails on EBUSY (dir in use
by another live mount) before failing on ESTALE (upper/lower dir
mismatch).
Never the less, fix the mismatch, so a change in the kernel between
the two sanity checks (EBUSY vs. ESTALE) won't break the test.

XFS headers are supposed to be included in a certain order so that
inline functions actually compile correctly. For the most part the
shell feeds us the files in an order that works, but with the
addition of the xfs_dir2_dirblock_bytes function this doesn't always
work now. Therefore, explicitly #include the headers in the
required order.
