The patchec5ce09875: "tracing: Allow whitespace to surround hist trigger filter" from Jan 15, 2018, leads to the following Smatch static checker warning: kernel/trace/trace_events_hist.c:6199 event_hist_trigger_parse() warn: 'p' can't be NULL. Since p is always checked for a NULL value at the top of loop and nothing in the rest of the loop will set it to NULL, the warning is correct and might as well be 1 to silence the warning.

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.
