| |
This is the third version of the timer wheel rework series. The previous versions can be found here:
V1: http://lkml.kernel.org/r/20160613070440.950649741@linutronix.de V2: http://lkml.kernel.org/r/20160617121134.417319325@linutronix.de
The series is also available in git:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.timers
Changes vs. V2:
- Removed the 1000Hz granularity reduction to 4ms. Eric explained that datacenter workloads require the granularity in the first level wheel.
- Fixed the typo in tilepro.
- Converted sigtimedwait() to hrtimers
- To avoid the cascading I extended the wheel by another level. This removes the rarely executed cascading code path, but increases the storage size for HZ>100 slightly. If the tiny folks care, there is an simple option to cut the storage size in half for the price of reduced granularity.
Thanks,
tglx
