overlay: test encode/decode of non-samefs overlay file handles with renames
This is a variant of overlay file handles with renames test for an overlayfs that is composed of multiple lower layers not on the same underlying fs. Signed-off-by: Amir Goldstein <amir73il@gmail.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>

# Test encode/decode of non-samefs overlay file handles with renames
|
||||
#
|
||||
# This is a variant of overlay file handles with renames test for an
|
||||
# overlayfs that is composed of multiple lower layers not on the same
|
||||
# underlying fs.
|
||||
#
|
||||
# - 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.
