In some situations, it is useful to explicitly specify a kernel module to search for a tracing program target (e.g. when a function of the same name exists in multiple modules or in vmlinux). This patch enables that by allowing the "module:function" syntax for the find_kernel_btf_id function. Thanks to this, the syntax can be used both from a SEC macro (i.e. `SEC(fentry/module:function)`) and via the bpf_program__set_attach_target API call.

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 reStructuredText 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.
