a old issue of ext4 on lts 3.10

by Alex Shi

Hi Dmitry&Theodore, Someone said without the following patch on lts 3.10 kernel (which used as android base kernel). the write maybe very very slow, needs 1 or 2 seconds to finish. I quick looked this patch, seems it's no harm for a normal fs function. but still don't know why it is helpful. So do you remember why you commit this change at that time?

[PATCH V5 00/14] cpufreq: Don't loose cpufreq history on CPU hotplug

by Viresh Kumar

Hi Rafael, The aim of this series is to stop managing cpufreq sysfs directories on CPU hotplug. Currently on removal of a 'cpu != policy->cpu', we remove its sysfs directories by removing the soft-link. And on removal of policy->cpu, we migrate the sysfs directories to the next cpu in policy. But if policy->cpu was the last CPU, we remove the policy completely and allocate it again once the CPUs come back. This has shortcomings: - Code Complexity - Slower hotplug - sysfs file permissions are reset after all policy->cpus are offlined - CPUFreq stats history lost after all policy->cpus are offlined - Special management of sysfs stuff during suspend/resume To make things simple we can stop playing with sysfs files unless the driver is getting removed. Also the policy can be kept intact to be used later. First few patches provide a clean base for others *more important* patches. Rebased-over: your linux-next branch as there were dependencies on my earlier patches. Pushed here: git://git.linaro.org/people/viresh.kumar/linux.git cpufreq/core/sysfs-v4 V4-V5: - Sending all patches again - Fixed comments in one of the patches as suggested by you - Merged the last commit about "physical hotplug of CPUs" with "cpufreq: Stop migrating sysfs files on hotplug". - A new patch (content is old, just separated out into its own patch) "cpufreq: add/remove sysfs links via cpufreq_add_remove_dev_symlink()" V3-V4: - Only four patches sent this time: - [PATCH V4 01/14] cpufreq: Create for_each_{in}active_policy() - [PATCH V4 04/14] cpufreq: Don't traverse all active policies to find - [PATCH V4 05/14] cpufreq: Manage governor usage history with - [PATCH V4 06/14] cpufreq: Mark policy->governor = NULL for inactive - Remove __temp from the arguments of for_each_[in]active_policies. - Simplified macros/next_policy, etc. V2->V3: - First five are already applied by you and the 7th one was sent separately as a fix earlier and got applied. So, V2 had 20 patches and V3 has 14. - Dropped while(1) and used do/while. - policy->governor marked as NULL only while removing the governor and not when policy becomes inactive. - Commit logs/comments updated - Applied Acks from Saravan v1->V2: - Dropped the idea of using policy-lists for getting policy for any cpu - Also dropped fallback list and its per-cpu variable - Stopped cleaning cpufreq_cpu_data and doing list_del(policy) on logical hotplug. - Added support for physical hotplug of CPUs (Untested). Saravana Kannan (1): cpufreq: Track cpu managing sysfs kobjects separately Viresh Kumar (13): cpufreq: Create for_each_{in}active_policy() cpufreq: Don't clear cpufreq_cpu_data and policy list for inactive policies cpufreq: Get rid of cpufreq_cpu_data_fallback cpufreq: Don't traverse all active policies to find policy for a cpu cpufreq: Manage governor usage history with 'policy->last_governor' cpufreq: Mark policy->governor = NULL for inactive policies cpufreq: Don't allow updating inactive policies from sysfs cpufreq: add/remove sysfs links via cpufreq_add_remove_dev_symlink() cpufreq: Stop migrating sysfs files on hotplug cpufreq: Remove cpufreq_update_policy() cpufreq: Initialize policy->kobj while allocating policy cpufreq: Call cpufreq_policy_put_kobj() from cpufreq_policy_free() cpufreq: Restart governor as soon as possible drivers/cpufreq/cpufreq.c | 486 +++++++++++++++++++++++++--------------------- include/linux/cpufreq.h | 5 +- 2 files changed, 268 insertions(+), 223 deletions(-) -- 2.4.0

[PATCH v2 LSK-v3.10] arm64: topology: fix cpu power calculation

by Jorge Ramirez-Ortiz

This commit sets the power of the average CPU in SMP systems to SCHED_CAPACITY_SCALE. Ignoring the condition "min_capacity==max_capacity" causes the function update_cpu_power( .. ) to generate out of range values [1]. This is because the default value of middle_capacity is used in the final calculation instead of a valid scaling factor. Incidentally, when out of range values are generated and if SCHED_FEAT(ARCH_POWER) is true) the load balancing algorithm makes the wrong decisions typically overallocating work on one of the cores while leaving the others unused.
