Currently, netconsole discards targets that fail during initialization,
causing two issues:
1) Inconsistency between target list and configfs entries
* user pass cmdline0, cmdline1. If cmdline0 fails, then cmdline1
becomes cmdline0 in configfs.
2) Inability to manage failed targets from userspace
* If user pass a target that fails with netpoll (interface not loaded at
netcons initialization time, such as interface is a module), then
the target will not exist in the configfs, so, user cannot re-enable
or modify it from userspace.
Failed targets are now added to the target list and configfs, but
remain disabled until manually enabled or reconfigured. This change does
not change the behaviour if CONFIG_NETCONSOLE_DYNAMIC is not set.

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.
