Subject: [linus:master] [rhashtable] 4fe9852927: stress-ng.msg.ops_per_sec 29.1% regression
Date: Thu, 21 May 2026 16:09:40 +0800 [thread overview]
Message-ID: <202605211540.d9ef9555-lkp@intel.com> (raw)
Hello,
kernel test robot noticed a 29.1% regression of stress-ng.msg.ops_per_sec on:
commit: 4fe985292709eeb6a4653c71660f893e26c2f2dd ("rhashtable: Bounce deferred worker kick through irq_work")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[still regression on linus/master d458a240344c4369bf6f3da203f2779515177738]
[still regression on linux-next/master e98d21c170b01ddef366f023bbfcf6b31509fa83]
testcase: stress-ng
config: x86_64-rhel-9.4
compiler: gcc-14
