Subject: perf evlist: Fix create_syswide_maps() not propagating maps
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8c0498b6891d7ca5c379c6283de7fc7fe8eebe5c;p=linux-beck.git

perf evlist: Fix create_syswide_maps() not propagating maps

Fix it by making it call perf_evlist__set_maps() instead of setting the
maps itself.
