X-Git-Tag: v6.12-rc1~109^2~210
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ae737b61029ced77391e2b850433cd316716ddf9;p=thirdparty%2Fkernel%2Fstable.git

perf tool: Add perf_tool__init()

Add init function that behaves like perf_tool__fill_defaults() but
assumes all values haven't been initialized.
