dasd_eckd_path_available_action() does a memory allocation to store the per path configuration data permanently. In the unlikely case that this allocation fails there is no conf_data stored for the corresponding path. This is OK since this is not necessary for an operational path but some features like control unit initiated reconfiguration (CUIR) do not work. To fix this add the path to the 'to be verified pathmask' again and schedule the handler again.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
