[PATCH v1 0/8] Address/leak sanitizer clean ups

From: Ian Rogers
Date: Tue May 07 2024 - 14:36:13 EST


Remove unnecessary reference counts for structs with no gets. Add
reference count checking to comm_str and mem_info. Fix memory leaks
and errors detected on "perf mem report" by address sanitizer and leak
sanitizer.

Ian Rogers (8):
perf ui browser: Don't save pointer to stack memory
perf annotate: Fix memory leak in annotated_source
perf block-info: Remove unused refcount
perf cpumap: Remove refcnt from cpu_aggr_map
perf comm: Add reference count checking to comm_str
perf mem-info: Move mem-info out of mem-events and symbol
perf mem-info: Add reference count checking
perf hist: Avoid hist_entry_iter mem_info memory leak
