17 12:35:15 2019 -0700 # # Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip # # Pull core timer updates from Thomas Gleixner: # "Timers and timekeeping updates: # # - A large overhaul of the posix CPU timer code which is a preparation # for moving the CPU timer expiry out into task work so it can be # properly accounted on the task/process. # # An update to the bogus permission checks will come later during the # merge window as feedback was not complete before heading of for # travel. # # - Switch the timerqueue code to use cached rbtrees and get rid of the # homebrewn caching of the leftmost node. # # - Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a # single function # # - Implement the separation of hrtimers to be forced to expire in hard # interrupt context even when PREEMPT_RT is enabled and mark the # affected timers accordingly. # # - Implement a mechanism for hrtimers and the timer wheel to protect # RT against priority inversion and live lock issues when a (hr)timer # which should be canceled is currently executing the callback. # Instead of infinitely spinning, the task which tries to cancel the # timer blocks on a per cpu base expiry lock which is held and # released by the (hr)timer expiry code. # # - Enable the Hyper-V TSC page based sched_clock for Hyper-V guests # resulting in faster access to timekeeping functions. # # - Updates to various clocksource/clockevent drivers and their device # tree bindings. # # - The usual small improvements all over the place" # # *
