* [GIT PULL] scheduler changes for v4.13 @ 2017-07-03 8:39 Ingo Molnar 2017-07-10 4:19 ` Florian Fainelli 0 siblings, 1 reply; 11+ messages in thread From: Ingo Molnar @ 2017-07-03 8:39 UTC (permalink / raw) To: Linus Torvalds Cc: linux-kernel, Peter Zijlstra, Thomas Gleixner, H. Peter Anvin, Andrew Morton, Mike Galbraith Linus, Please pull the latest sched-core-for-linus git tree from: git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-core-for-linus # HEAD: 72298e5c92c50edd8cb7cfda4519483ce65fa166 sched/cputime: Refactor the cputime_adjust() code The main changes in this cycle were: - Add the SYSTEM_SCHEDULING bootup state to move various scheduler debug checks earlier into the bootup. This turns silent and sporadically deadly bugs into nice, deterministic splats. Fix some of the splats that triggered. (Thomas Gleixner) - A round of restructuring and refactoring of the load-balancing and topology code (Peter Zijlstra) - Another round of consolidating ~20 of incremental scheduler code history: this time in terms of wait-queue nomenclature. (I didn't get much feedback on these renaming patches, and we can still easily change any names I might have misplaced, so if anyone hates a new name, please holler and I'll fix it.) (Ingo Molnar) - sched/numa improvements, fixes and updates (Rik van Riel) - Another round of x86/tsc scheduler clock code improvements, in hope of making it more robust (Peter Zijlstra) - Improve NOHZ behavior (Frederic Weisbecker) - Deadline scheduler improvements and fixes (Luca Abeni, Daniel Bristot de Oliveira) - Simplify and optimize the topology setup code (Lauro Ramos Venancio) - Debloat and decouple scheduler code some more (Nicolas Pitre) - Simplify code by making better use of llist primitives (Byungchul Park) - ... plus other fixes and improvements.

Was it intentional to force an user space build breakage when building against v4.13-rc headers for autofs headers? Thanks -- Florian ^ permalink raw reply [flat|nested] 11+ messages in thread
