Subject: [PATCH 12/20] perf script: release zstd data
Date: Thu, 15 Jul 2021 18:07:17 +0200	[thread overview]
Message-ID: <39388e8cc2f85ca219ea18697a17b7bd8f74b693.1626343282.git.rickyman7@gmail.com> (raw)
In-Reply-To: <cover.1626343282.git.rickyman7@gmail.com>

ASan reports several memory leak while running the perf test
"82: Use vfs_getname probe to get syscall args filenames".
One of the leaks is caused by zstd data not being released on exit in
perf-script.

This patch adds the missing zstd_fini.
