2014-12-08f2fs: fix to enable readahead for SSA/CP blocksChao Yu
1.We use zero as upper boundary value for ra SSA/CP blocks, we will skip readahead as verification failure with max number, it causes low performance. 2.Low boundary value is not accurate for SSA/CP/POR region verification, so these values need to be redefined. This patch fixes above issues. Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

2014-12-08thermal: cpu_cooling: Use cpufreq_dev->freq_table for finding level/freqViresh Kumar
get_property() was an over complicated beast with BUGs. It used to believe that cpufreq table is present in ascending or descending order, which might not always be true. Previous patch has created another freq table in descending order for us and we better use it now. With that get_property() simply goes away and another helper get_level() comes in.

2014-12-08thermal: cpu_cooling: Store frequencies in descending orderViresh Kumar
CPUFreq framework *doesn't* guarantee that frequencies present in cpufreq table will be in ascending or descending order. But cpu_cooling somehow assumes that. Probably because most of current users are creating this list from DT, which is done with the help of OPP layer. And OPP layer creates the list in ascending order of frequencies. But cpu_cooling can be used for other platforms too, which don't have frequencies arranged in any order. This patch tries to fix this issue by creating another list of valid frequencies in descending order. Care is also taken to throw warnings for duplicate entries. Later patches would use it to simplify code. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
2014-12-08thermal: cpu_cooling: Pass 'cpufreq_dev' to get_property()Viresh Kumar
We already know the value of 'cpufreq_dev->max_level' and so there is no need calculating that once again. For this, we need to send 'cpufreq_dev' to get_property(). Make all necessary changes for this change. Because cpufreq_cooling_get_level() doesn't have access to 'cpufreq_dev', it is updated to iterate over the list of cpufreq_cooling_devices to get cooling device for the cpu number passed to it. This also makes it robust to return levels only for the CPU registered via a cooling device. We don't have to support anything that isn't registered yet.

2014-12-08workqueue: allow rescuer thread to do more work.NeilBrown
When there is serious memory pressure, all workers in a pool could be blocked, and a new thread cannot be created because it requires memory allocation. In this situation a WQ_MEM_RECLAIM workqueue will wake up the rescuer thread to do some work. The rescuer will only handle requests that are already on ->worklist. If max_requests is 1, that means it will handle a single request. The rescuer will be woken again in 100ms to handle another max_requests requests. I've seen a machine (running a 3.0 based "enterprise" kernel) with thousands of requests queued for xfslogd, which has a max_requests of 1, and is needed for retiring all 'xfs' write requests. When one of the worker pools gets into this state, it progresses extremely slowly and possibly never recovers (only waited an hour or two). With this patch we leave a pool_workqueue on mayday list until it is clearly no longer in need of assistance. This allows all requests to be handled in a timely fashion. We keep each pool_workqueue on the mayday list until need_to_create_worker() is false, and no work for this workqueue is found in the pool. I have tested this in combination with a (hackish) patch which forces all work items to be handled by the rescuer thread. In that context it significantly improves performance. A similar patch for a 3.0 kernel significantly improved performance on a heavy work load. Thanks to Jan Kara for some design ideas, and to Dongsu Park for some comments and testing. tj: Inverted the lock order between wq_mayday_lock and pool->lock with a preceding patch and simplified this patch. Added comment and updated changelog accordingly. Dongsu spotted missing get_pwq() in the simplified code.

2014-12-08workqueue: invert the order between pool->lock and wq_mayday_lockTejun Heo
Currently, pool->lock nests inside pool->lock. There's no inherent reason for this order. The only place where the two locks are held together is pool_mayday_timeout() and it just got decided that way. This nesting order turns out to complicate things with the planned rescuer_thread() update. Let's invert them. This doesn't cause any behavior differences.

2014-12-08thermal: cpu_cooling: don't iterate over all allowed_cpus to update cpufreq ↵Viresh Kumar
policy All CPUs present in 'allowed_cpus' share the same 'struct cpufreq_policy' structure and so calling cpufreq_update_policy() for each of them doesn't make sense. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
2014-12-08thermal: cpu_cooling: Don't match min/max frequencies for all CPUs on ↵Viresh Kumar
cooling register In __cpufreq_cooling_register() we try to match min/max frequencies for all CPUs passed in 'clip_cpus' mask. This mask is the cpumask of cpus where the frequency constraints will be applied. Same frequency constraint can be applied only to the CPUs belonging to the same cluster (i.e. CPUs sharing clock line). For all such CPUs we have a single 'struct cpufreq_policy' structure managing them and so getting policies for all CPUs wouldn't make any sense as they will all return the same pointer. So, remove this useless check of checking min/max for all CPUs. Also update doc comment to make this more obvious that clip_cpus should be same as policy->related_cpus.

We aren't supposed to return our own error type here. Return what we got. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
