>From commit282de143ea("bpf: Introduce allocated objects support"), With this allocated object with BPF program, (PTR_TO_BTF_ID | MEM_ALLOC) has been a way of indicating to check the type is the allocated object. commitd8939cb0a0("bpf: Loosen alloc obj test in verifier's reg_btf_record") >From the commit, there has been helper function for checking this, named type_is_ptr_alloc_obj(). But still, some of the code use open code to retrieve this info. This commit replaces the open code with the type_is_alloc(), and the type_is_ptr_alloc_obj() function. Signed-off-by: Daniel T.

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.
