Subject: [linus:master] [timers] 7ee9887703: stress-ng.uprobe.ops_per_sec
-17.1% regression
Hello,
we reported
"[tip:timers/core] [timers] 7ee9887703: netperf.Throughput_Mbps -1.2% regression"
in
https://lore.kernel.org/all/202403011511.24defbbd-oliver.sang@intel.com/
now we noticed this commit is in mainline and we captured further results.
still include netperf results for complete. below details FYI.
kernel test robot noticed a -17.1% regression of stress-ng.uprobe.ops_per_sec on:
commit: 7ee988770326fca440472200c3eb58935fe712f6 ("timers: Implement the hierarchical pull model")
