Yunfeng proposed a change to tick_do_update_jiffies64() to reduce the contention on jiffies_seq sequence counter:
https://lore.kernel.org/r/[email protected] This made me look deeper and there are lots of other things to optimize, but also things to document which are completely undocumented today. The lot is based on git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers/core and also available via git from: git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git tick Thanks, tglx
