The .check_member field of struct bpf_struct_ops is currently passed the member's btf_type via const struct btf_type *t, and a const struct btf_member *member. This allows the struct_ops implementation to check whether e.g. an ops is supported, but it would be useful to also enforce that the struct_ops prog being loaded for that member has other qualities, like being sleepable (or not). This patch therefore updates the .check_member() callback to also take a const struct bpf_prog *prog argument.

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.
