| From | Riccardo Mancini <> | Subject | [PATCH 14/20] perf util/lzma: close lzma stream | Date | Thu, 15 Jul 2021 18:07:19 +0200 |
| |
ASan reports memory leaks when running the perf test "88: Check open filename arg using perf trace + vfs_getname". One of these is caused by the lzma stream never being closed inside lzma_decompress_to_file.
This patch adds the missing lzma_end.
