hi, Oleg Nesterov, we reported "[brauner-vfs:vfs-6.14.misc] [pipe_read] aaec5a95d5: hackbench.throughput 7.5% regression" in https://lore.kernel.org/all/202501101015.90874b3a-lkp@xxxxxxxxx/ but seems both you and Christian Brauner think it could be ignored. now we captured a regression in another test case. since e.g. there are something like below in perf data, not sure if it could supply any useful information? just FYI. sorry if it's still not with big value. 9.45 -6.3 3.13 ± 9% perf-profile.calltrace.cycles-pp.pipe_read.vfs_read.ksys_read.do_syscall_64.entry_SYSCALL_64_after_hwframe ...
