Subject: perf evlist: Factor out a function to propagate maps for a single evsel
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=adc0c3e87b0e1baeccabe09b6dba738f17d0e91d;p=openwrt%2Fstaging%2Fblogic.git

perf evlist: Factor out a function to propagate maps for a single evsel

Subsequent fixes will need a function that just propagates maps for a
single evsel so factor it out.

[ Moved them to before perf_evlist__add() to avoid having to move it in the next patch ]
