Alexei Starovoitov says: ==================== bpf: stack depth tracking Introduce tracking of bpf program stack depth in the verifier and use that info to reduce bpf program stack consumption in the interpreter and x64 JIT. Other JITs can take advantage of it as well in the future. Most of the programs consume very little stack, so it's good optimization in general and it's the first step toward bpf to bpf function calls. Also use internal opcode for bpf_tail_call() marking to make clear that jmp|call|x opcode is not uapi and may be used for actual indirect call opcode in the future. ==================== Signed-off-by: David S.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
