6.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Adrian Hunter <adrian.hunter@xxxxxxxxx>
[ Upstream commit 792bc998baf9ae17297b1f93b1edc3ca34a0b7e2 ]
evlist__config() might mess up the debug output consumed by test
"Test per-thread recording" in "Miscellaneous Intel PT testing".
Move it out from between the debug prints:
"perf record opening and mmapping events" and
"perf record done opening and mmapping events"
Fixes: da4062021e0e6da5 ("perf tools: Add debug messages and comments for testing")
Closes: https://lore.kernel.org/linux-perf-users/ZhVfc5jYLarnGzKa@x1/
