Two list heads in the rdma_id_private are being used for multiple purposes, to save a few bytes of memory. Give the different purposes different names and union the memory that is clearly exclusive. list splits into device_item and listen_any_item. device_item is threaded onto the cma_device's list and listen_any goes onto the listen_any_list. IDs doing any listen cannot have devices. listen_list splits into listen_item and listen_list. listen_list is on the parent listen any rdma_id_private and listen_item is on child listen that is bound to a specific cma_dev. Which name should be used in which case depends on the state and other factors of the rdma_id_private. Remap all the confusing references to make sense with the new names, so at least there is some hope of matching the necessary preconditions with each access.

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.
