* percpu_rw_semaphore: add lockdep annotationsOleg Nesterov2012-12-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add lockdep annotations. Not only this can help to find the potential problems, we do not want the false warnings if, say, the task takes two different percpu_rw_semaphore's for reading. IOW, at least ->rw_sem should not use a single class. This patch exposes this internal lock to lockdep so that it represents the whole percpu_rw_semaphore. This way we do not need to add another "fake" ->lockdep_map and lock_class_key. More importantly, this also makes the output from lockdep much more understandable if it finds the problem. In short, with this patch from lockdep pov percpu_down_read() and percpu_up_read() acquire/release ->rw_sem for reading, this matches the actual semantics. This abuses __up_read() but I hope this is fine and in fact I'd like to have down_read_no_lockdep() as well, percpu_down_read_recursive_readers() will need it.

* percpu_rw_semaphore: kill ->writer_mutex, add ->write_ctrOleg Nesterov2012-12-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | percpu_rw_semaphore->writer_mutex was only added to simplify the initial rewrite, the only thing it protects is clear_fast_ctr() which otherwise could be called by multiple writers. ->rw_sem is enough to serialize the writers. Kill this mutex and add "atomic_t write_ctr" instead. The writers increment/decrement this counter, the readers check it is zero instead of mutex_is_locked(). Move atomic_add(clear_fast_ctr(), slow_read_ctr) under down_write() to avoid the race with other writers. This is a bit sub-optimal, only the first writer needs this and we do not need to exclude the readers at this stage. But this is simple, we do not want another internal lock until we add more features. And this speeds up the write-contended case. Before this patch the racing writers sleep in synchronize_sched_expedited() sequentially, with this patch multiple synchronize_sched_expedited's can "overlap" with each other. Note: we can do more optimizations, this is only the first step.

* percpu_rw_semaphore: reimplement to not block the readers unnecessarilyOleg Nesterov2012-12-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the writer does msleep() plus synchronize_sched() 3 times to acquire/release the semaphore, and during this time the readers are blocked completely. Even if the "write" section was not actually started or if it was already finished. With this patch down_write/up_write does synchronize_sched() twice and down_read/up_read are still possible during this time, just they use the slow path. percpu_down_write() first forces the readers to use rw_semaphore and increment the "slow" counter to take the lock for reading, then it takes that rw_semaphore for writing and blocks the readers. Also. With this patch the code relies on the documented behaviour of synchronize_sched(), it doesn't try to pair synchronize_sched() with barrier.

* sscanf: don't ignore field widths for numeric conversionsJan Beulich2012-12-17
| | | | | | | | | | | | | | | | | | This is another step towards better standard conformance. Rather than adding a local buffer to store the specified portion of the string (with the need to enforce an arbitrary maximum supported width to limit the buffer size), do a maximum width conversion and then drop as much of it as is necessary to meet the caller's request. Also fail on negative field widths. Uses the deprecated simple_strto*() functions because kstrtoXX() fail on non-zero terminated strings.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The LP855x family devices support the PWM input for the backlight control. Period of the PWM is configurable in the platform side. Platform specific functions are unnecessary anymore because generic PWM functions are used inside the driver. (PWM input mode) To set the brightness, new lp855x_pwm_ctrl() is used. If a PWM device is not allocated, devm_pwm_get() is called. The PWM consumer name is from the chip name such as 'lp8550' and 'lp8556'. To get the brightness value, no additional handling is required. Just the value of 'props.brightness' is returned. If the PWM driver is not ready while initializing the LP855x driver, it's OK. The PWM device can be retrieved later, when the brightness value is changed. Documentation is updated with an example.
