# HEAD: da65f29dada7f7cbbf0d6375b88a0316f5f7d6f5 timers: Fix nextevt calculation when no timers are pending
Timer subsystem changes for v6.8:
- Various preparatory cleanups & enhancements of the timer-wheel code,
in preparation for the WIP 'pull timers at expiry' timer migration model
series (which will replace the current 'push timers at enqueue' migration
model), by Anna-Maria Behnsen:
- Update comments and clean up confusing variable names
- Add debug check to warn about time travel
- Improve/expand timer-wheel tracepoints
- Optimize away unnecessary IPIs for deferrable timers
- Restructure & clean up next_expiry_recalc()
- Clean up forward_timer_base()
- Introduce __forward_timer_base() and use it to simplify
and micro-optimize get_next_timer_interrupt()
- Restructure the get_next_timer_interrupt()'s idle logic
for better readability and to enable a minor optimization.
- Fix the nextevt calculation when no timers are pending
- Fix the sysfs_get_uname() prototype declaration
Thanks,
Ingo
