[PATCH 08/12] perf jitdump: Free event in jit_repipe_code_move()

From: Arnaldo Carvalho de Melo

Date: Thu Aug 06 2026 - 08:38:05 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

jit_repipe_code_move() allocates a perf_event with calloc but never
frees it — the 'out' label exits with only perf_sample__exit().

The sibling function jit_repipe_code_load() correctly calls
free(event) at its out label. Add the same free(event) to
jit_repipe_code_move().

Fixes: 9b07e27f88b9 ("perf inject: Add jitdump mmap injection support")
