# Test encode/decode overlay file handles for non-samefs.
|

#
|
||||
# This is a variant of overlay file handles test for an overlayfs that is
|
||||
# composed of multiple lower layers not on the same underlying fs.
|
||||
#
|
||||
# - Check encode/write/decode/read content of lower/upper file handles
|
||||
# - Check encode/decode/write/read content of lower/upper file handles
|
||||
# - Check decode/read of unlinked lower/upper files and directories
|
||||
# - Check decode/read of lower file handles after copy up, link and unlink
|
||||
#
|
||||
# This test requires and enables overlayfs NFS export support.
|
||||
# NFS export support depends on and requires overlayfs index feature.
