[PATCH v2 11/16] perf python: Zero initialize perf_data in pyrf_data__init

From: Ian Rogers

Date: Wed Jun 24 2026 - 01:20:59 EST


Replace path clearing with memset so the entire struct is zeroed,
preventing uninitialized fields from causing errors later.

Fixes: 4cd0142f7dec ("perf python: Add wrapper for perf_data file abstraction")
