Subject: [PATCH 10/15] perf config: Document missing config options
Date: Fri, 28 Feb 2020 11:00:09 -0300 [thread overview]
Message-ID: <20200228140014.1236-11-acme@kernel.org> (raw)
In-Reply-To: <20200228140014.1236-1-acme@kernel.org>
From: Ravi Bangoria <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.
