From: Tom Zanussi <tom.zanussi@xxxxxxxxxxxxxxx> Hi, This patchset is a standalone series broken out of the v8 version of the 'tracing: Hist trigger snapshot and onchange additions' patchset. It's a series of changes resulting from some suggestions from Namhyung for making the variable-reference handling code more understandable through some refactoring and comments. It also added a new patch changing all strlen() to sizeof() for string constants, in trace_events_hist.c Also, in the 'tracing: Remove open-coding of hist trigger var_ref management' patch, in create_var_ref(), moved the saving of ref_field and update of ref_field->var_ref_idx into the 'if' as pointed out by Dan Carpenter/smatch 0-day robot. It doesn't introduce any functional changes and can be applied independently of the other patchset.
