Subject: [PATCH] perf data: close all files in close_dir
Date: Mon, 21 Jun 2021 23:42:19 +0200 [thread overview]
Message-ID: <20210621214220.167927-1-rickyman7@gmail.com> (raw)
When using perf report in directory mode, the first file is not closed on
exit, causing a memory leak.
The problem is caused by the iterating variable never reaching 0.
