Yafang also optimized root cgroup list access by making it # RCU protected in the process. # # - Waiman Long optimized rstat operation leading to substantially lower # and more consistent lock hold time while flushing the hierarchical # statistics. As the lock can be acquired briefly in various hot paths, # this reduction has cascading benefits. # # - Waiman also improved the quality of isolation for cpuset's isolated # partitions. CPUs which are allocated to isolated partitions are now # excluded from running unbound work items and cpu_is_isolated() test # which is used by vmstat and memcg to reduce interference now includes # cpuset isolated CPUs. While it isn't there yet, the hope is # eventually reaching parity with the isolation level provided by the # `isolcpus` boot param but in a dynamic manner. # # * tag 'cgroup-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: # cgroup: Move rcu_head up near the top of cgroup_root # cgroup/cpuset: Include isolated cpuset CPUs in cpu_is_isolated() check # cgroup: Avoid false cacheline sharing of read mostly rstat_cpu # cgroup/rstat: Optimize cgroup_rstat_updated_list() # cgroup: Fix documentation for cpu.idle # cgroup/cpuset: Expose cpuset.cpus.isolated # workqueue: Move workqueue_set_unbound_cpumask() and its helpers inside CONFIG_SYSFS # cgroup/rstat: Reduce cpu_lock hold time in cgroup_rstat_flush_locked() # cgroup/cpuset: Take isolated CPUs out of workqueue unbound cpumask # cgroup/cpuset: Keep track of CPUs in isolated partitions # selftests/cgroup: Minor code cleanup and reorganization of test_cpuset_prs.sh # workqueue: Add workqueue_unbound_exclude_cpumask() to exclude CPUs from wq_unbound_cpumask # selftests: cgroup: Fixes a typo in a comment # cgroup: Add a new helper for cgroup1 hierarchy # cgroup: Add annotation for holding namespace_sem in current_cgns_cgroup_from_root() # cgroup: Eliminate the need for cgroup_mutex in proc_cgroup_show() # cgroup: Make operations on the cgroup root_list RCU safe # cgroup: Remove unnecessary list_empty() # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 9f8413c4a66f2fb776d3dc3c9ed20bf435eb305e # make -s -j 32 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 allyesconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig CONFIG_BPF_PRELOAD=n # Added to kconfig CONFIG_SPI_STM32_QSPI=n # < make -s -j 32 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 help # make -s -j 32 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig .config:14264:warning: override: reassigning to symbol GCC_PLUGIN_LATENT_ENTROPY .config:14268:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:14270:warning: override: reassigning to symbol UML_NET_SLIP .config:14275:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 32 ARCH=um O=/kisskb/build/linus_allyesconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 LINK linux Completed OK # rm -rf /kisskb/build/linus_allyesconfig_um-x86_64-gcc12 # Build took: 0:18:55.518371
