[PATCH 1/7] tracing: fix printk format specifier

[Steven Rostedt <rostedt@goodmis.org>]

[-- Attachment #1: 0001-tracing-fix-printk-format-specifier.patch --]
[-- Type: text/plain, Size: 1646 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

Impact: clean up

The offsetof and sizeof are of type size_t, and instead of typecasting
them to unsigned int for printk formatting, one could just use %zu.
