## `path`

The `path` data type represents kernel `struct path` object retrieves
the related path.

{{< caution >}}
Full path retrieval is available only on kernels `v5.3` and later.

On older kernels, there's a limit of 256 path components, which means
we can retrieve up to the maximum path length (4096 bytes), but only
with 256 path entries (directories and file name).
