From: Riccardo Mancini <rickyman7@gmail.com> stable inclusion from stable-5.10.54 commit a2f0da3af61455cdd86dc13bc305e50db58a5b08 bugzilla: 175586 https://gitee.com/openeuler/kernel/issues/I4DVDU Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ 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.
