The story is that Smatch marks skb->data as untrusted so it generates
a warning message here:
drivers/infiniband/hw/cxgb4/cm.c:4100 process_work()
error: buffer overflow 'work_handlers' 241 <= 255
In other places which handle this such as t4_uld_rx_handler() there is
some checking to make sure that the function pointer is not NULL. I
have added bounds checking and a check for NULL here as well.

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.
