Yes, it's better to get more details of which fields are hottest, and following are some perf data details. Let me know if more info is needed. * perf-stat: we see more cache-misses 32158577 ± 7% +9.0% 35060321 ± 6% perf-stat.ps.cache-misses 69612918 ± 6% +11.2% 77382336 ± 5% perf-stat.ps.cache-references * perf profile: the 'mmap_lock' are the hottest, though the ratio from map/unmap has some difference from 72:24 to 52:45, and this is the part that I don't understand - old kernel (without commit 57efa1fe59) 96.60% 0.19% [kernel.kallsyms] [k] down_write_killable - - 72.46% down_write_killable;vm_mmap_pgoff;ksys_mmap_pgoff;do_syscall_64;entry_SYSCALL_64_after_hwframe;__mmap 24.14% down_write_killable;__vm_munmap;__x64_sys_munmap;do_syscall_64;entry_SYSCALL_64_after_hwframe;__munmap - new kernel 96.60% 0.16% [kernel.kallsyms] [k] down_write_killable - - 51.85% down_write_killable;vm_mmap_pgoff;ksys_mmap_pgoff;do_syscall_64;entry_SYSCALL_64_after_hwframe;__mmap 44.74% down_write_killable;__vm_munmap;__x64_sys_munmap;do_syscall_64;entry_SYSCALL_64_after_hwframe;__munmap * perf-c2c: The hotspots(HITM) for 2 kernels are different due to the data structure change - old kernel - first cacheline mmap_lock->count (75%) mm->mapcount (14%) - second cacheline mmap_lock->owner (97%) - new kernel mainly in the cacheline of 'mmap_lock' mmap_lock->count (~2%) mmap_lock->owner (95%) I also attached the reduced pah and perf-c2c log for further check. (The absolute HITM events number can be ignored, as the recording time for new/old kernel may be different) > It would be great to have a comment in the code - and in the commit > message - about exactly which fields are the criticial ones.

Ok, will add more comments if the patch is still fine with the above updated info.
