In the accepted series "Refactor ib_uverbs_write path", we presented the roadmap to get rid of uverbs_cmd_mask and uverbs_ex_cmd_mask fields in favor of simple check of function pointer. So let's put NULL check of create_flow function callback despite the fact that uverbs_ex_cmd_mask still exists.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
