This is an opt-in feature that requires the enabling of # the LATENCY_WARN scheduler feature, or the use of the # resched_latency_warn_ms=xx boot parameter. # # - CPU hotplug fixes for HP-rollback, and for the 'fail' interface. Fix # remaining balance_push() vs. hotplug holes/races # # - PSI fixes, plus allow /proc/pressure/ files to be written by # CAP_SYS_RESOURCE tasks as well # # - Fix/improve various load-balancing corner cases vs. capacity margins # # - Fix sched topology on systems with NUMA diameter of 3 or above # # - Fix PF_KTHREAD vs to_kthread() race # # - Minor rseq optimizations # # - Misc cleanups, optimizations, fixes and smaller updates # # * tag 'sched-core-2021-04-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (61 commits) # cpumask/hotplug: Fix cpu_dying() state tracking # kthread: Fix PF_KTHREAD vs to_kthread() race # sched/debug: Fix cgroup_path[] serialization # sched,psi: Handle potential task count underflow bugs more gracefully # sched: Warn on long periods of pending need_resched # sched/fair: Move update_nohz_stats() to the CONFIG_NO_HZ_COMMON block to simplify the code & fix an unused function warning # sched/debug: Rename the sched_debug parameter to sched_verbose # sched,fair: Alternative sched_slice() # sched: Move /proc/sched_debug to debugfs # sched,debug: Convert sysctl sched_domains to debugfs # debugfs: Implement debugfs_create_str() # sched,preempt: Move preempt_dynamic to debug.c # sched: Move SCHED_DEBUG sysctl to debugfs # sched: Don't make LATENCYTOP select SCHED_DEBUG # sched: Remove sched_schedstats sysctl out from under SCHED_DEBUG # sched/numa: Allow runtime enabling/disabling of NUMA balance without SCHED_DEBUG # sched: Use cpu_dying() to fix balance_push vs hotplug-rollback # cpumask: Introduce DYING mask # cpumask: Make cpu_{online,possible,present,active}() inline # rseq: Optimise rseq_get_rseq_cs() and clear_rseq_cs() # ... # < /opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-gcc --version # < /opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-ld --version # < git log --format=%s --max-count=1 16b3d0cf5bad844daaf436ad2e9061de0fe36e5c # < make -s -j 48 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 48 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- help # make -s -j 48 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- olddefconfig # make -s -j 48 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- In file included from /kisskb/src/arch/xtensa/include/asm/atomic.h:19:0, from /kisskb/src/include/linux/atomic.h:7, from /kisskb/src/include/linux/page_counter.h:5, from /kisskb/src/mm/memcontrol.c:28: /kisskb/src/mm/memcontrol.c: In function 'memcg_reparent_objcgs': /kisskb/src/arch/xtensa/include/asm/cmpxchg.h:173:3: warning: value computed is not used [-Wunused-value] ((__typeof__(*(ptr)))__xchg((unsigned long)(x),(ptr),sizeof(*(ptr)))) ^ /kisskb/src/mm/memcontrol.c:336:2: note: in expansion of macro 'xchg' xchg(&objcg->memcg, parent);
