Mykyta Yatsenko says: ==================== bpf: Add _impl suffix for kfuncs with implicit args We have established a pattern of function naming win "_impl" suffix; those functions accept verifier-provided bpf_prog_aux argument. Following uniform convention will allow for transparent backwards compatibility with the upcoming KF_IMPLICIT_ARGS feature. This patch set aims to fix current deviation from the convention to eliminate unnecessary backwards incompatibility in the future. Three kfuncs added in 6.18 don’t follow this *_impl convention and therefore won’t participate in the new KF_IMPLICIT_ARGS mechanism: * bpf_task_work_schedule_resume() * bpf_task_work_schedule_signal() * bpf_stream_vprintk() Rename them to align with the implicit-arg flow: bpf_task_work_schedule_resume() -> bpf_task_work_schedule_resume_impl() bpf_task_work_schedule_signal() -> bpf_task_work_schedule_signal_impl() bpf_stream_vprintk() -> bpf_stream_vprintk_impl() The KF_IMPLICIT_ARGS mechanism is not in tree yet, so callers must switch to the *_impl names for now. Once the new mechanism lands, the plain names (without _impl) will be reintroduced.

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.
