Subject: perf test type profiling: Remote typedef on struct
X-Git-Tag: v7.1-rc1~91^2~113

perf test type profiling: Remote typedef on struct

The typedef creates an issue where the struct or the typedef may
appear in the output and cause the "perf data type profiling tests" to
fail. Let's remove the typedef to keep the test passing.
