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/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 9f8413c4a66f2fb776d3dc3c9ed20bf435eb305e # make -s -j 160 ARCH=sh O=/kisskb/build/linus_allmodconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-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 160 ARCH=sh O=/kisskb/build/linus_allmodconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 160 ARCH=sh O=/kisskb/build/linus_allmodconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 160 ARCH=sh O=/kisskb/build/linus_allmodconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h :1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:85: Warning: overflow in branch to __restore_all; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:357: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:360: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence {standard input}: Assembler messages: {standard input}:1094: Warning: end of file not at end of a line; newline inserted {standard input}:1095: Error: expected symbol name sh4-linux-gcc: internal compiler error: Segmentation fault signal terminated program cc1 Please submit a full bug report, with preprocessed source (by using -freport-bug).
