Leon Hwang says: ==================== bpf, verifier: Correct tail_call_reachable for bpf prog It's confusing to inspect 'prog->aux->tail_call_reachable' with drgn[0], when bpf prog has tail call but 'tail_call_reachable' is false. This patch corrects 'tail_call_reachable' when bpf prog has tail call. Therefore, it's unnecessary to detect tail call in x86 jit. Let's remove it. Changes: v1 -> v2: * Address comment from Yonghong: * Remove unnecessary tail call detection in x86 jit.

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.
