Currently the syscall trace events show each value as hexadecimal, but without adding "0x" it can be confusing: sys_write(fd: 4, buf: 0x55c4a1fa9270, count: 44) Looks like the above write wrote 44 bytes, when in reality it wrote 68 bytes. Add a "0x" for all values greater or equal to 10 to remove the ambiguity. For values less than 10, leave off the "0x" as that just adds noise to the output. Also change the iterator to check if "i" is nonzero and print the ", " delimiter at the start, then adding the logic to the trace_seq_printf() at the end.

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.
