Subject[PATCH 5.13 057/223] perf test maps__merge_in: Fix memory leak of maps
Date
From: Riccardo Mancini <rickyman7@gmail.com>

[ Upstream commit 244d1797c8c8e850b8de7992af713aa5c70d5650 ]

ASan reports a memory leak when running:

# perf test "65: maps__merge_in"

This is the second and final patch addressing these memory leaks.

This time, the problem is simply that the maps object is never
destructed.

This patch adds the missing maps__exit call.
