Remove the ib_is_destroyable_retryable() concept. The idea here was to allow the drivers to forcibly clean the HW object even if they otherwise didn't want to (eg because of usecnt). This was an attempt to clean up in a world where drivers were not allowed to fail HW object destruction. Now that we are going back to allowing HW objects to fail destroy this doesn't make sense. Instead if a uobject's HW object can't be destroyed it is left on the uobject list and it is up to uverbs_destroy_ufile_hw() to clean it. Multiple passes over the uobject list allow hidden dependencies to be resolved. If that fails the HW driver is broken, throw a WARN_ON and leak the HW object memory. All the other tricky failure paths (eg on creation error unwind) have already been updated to this new model.

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.
