drivers/net/ethernet/chelsio/cxgb4/sched.h declares a sched_class struct which has a type name clash with struct sched_class in kernel/sched/sched.h (a type used in a field in task_struct). When cxgb4 is a builtin we end up with both sched_class types, and as a result of this we wind up with DWARF (and derived from that BTF) with a duplicate incorrect task_struct representation. When cxgb4 is built-in this type clash can cause kernel builds to fail as resolve_btfids will fail when confused which task_struct to use. See [1] for more details. As such, renaming sched_class to ch_sched_class (in line with other structs like ch_sched_flowc) makes sense.

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.
