Subject: [PATCH 08/12] perf jitdump: Free event in jit_repipe_code_move()
Date: Thu,  6 Aug 2026 09:35:59 -0300	[thread overview]
Message-ID: <20260806123604.271277-9-acme@kernel.org> (raw)
In-Reply-To: <20260806123604.271277-1-acme@kernel.org>

From: Arnaldo Carvalho de Melo <acme@redhat.com>

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")
