Getting LLVM
-------------
+We provide prebuilt stable versions of LLVM on `kernel.org <https://kernel.org/pub/tools/llvm/>`_.
+Below are links that may be useful for building LLVM from source or procuring
+it through a distribution's package manager.
+
- https://releases.llvm.org/download.html
- https://github.com/llvm/llvm-project
- https://llvm.org/docs/GettingStarted.html
Reserve max(window/2^tcp_app_win, mss) of window for application
buffer. Value 0 is special, it means that nothing is reserved.
+ Possible values are [0, 31], inclusive.

Default: 31
