commit46c1e0621aupstream. Clang warns: net/netfilter/nf_conntrack_core.c:2068:21: warning: variable 'ctinfo' is uninitialized when used here [-Wuninitialized] nf_ct_set(skb, ct, ctinfo); ^~~~~~ net/netfilter/nf_conntrack_core.c:2024:2: note: variable 'ctinfo' is declared here enum ip_conntrack_info ctinfo; ^ 1 warning generated. nf_conntrack_update was split up into nf_conntrack_update and __nf_conntrack_update, where the assignment of ctinfo is in nf_conntrack_update but it is used in __nf_conntrack_update. Pass the value of ctinfo from nf_conntrack_update to __nf_conntrack_update so that uninitialized memory is not used and everything works properly.

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.
