Subject: [PATCH 8/8] perf config: Document missing config options
Date: Thu, 13 Feb 2020 12:13:06 +0530 [thread overview]
Message-ID: <20200213064306.160480-9-ravi.bangoria@linux.ibm.com> (raw)
In-Reply-To: <20200213064306.160480-1-ravi.bangoria@linux.ibm.com>
While documenting annotate.show_nr_samples config option, I found many
other config options missing in perf-config documentation. Add them.
