2012-02-09staging: line6: separate handling of buffer allocation and stream startupMarkus Grabner
There are several features of the Line6 USB driver which require PCM data to be exchanged with the device: *) PCM playback and capture via ALSA *) software monitoring (for devices without hardware monitoring) *) optional impulse response measurement However, from the device's point of view, there is just a single capture and playback stream, which must be shared between these subsystems. It is therefore necessary to maintain the state of the subsystems with respect to PCM usage. We define several constants of the form LINE6_BIT_PCM_<subsystem>_<direction>_<resource> with the following meanings: *) <subsystem> is one of -) ALSA: PCM playback and capture via ALSA -) MONITOR: software monitoring -) IMPULSE: optional impulse response measurement *) <direction> is one of -) PLAYBACK: audio output (from host to device) -) CAPTURE: audio input (from device to host) *) <resource> is one of -) BUFFER: buffer required by PCM data stream -) STREAM: actual PCM data stream The subsystems call line6_pcm_acquire() to acquire the (shared) resources needed for a particular operation (e.g., allocate the buffer for ALSA playback or start the capture stream for software monitoring). When a resource is no longer needed, it is released by calling line6_pcm_release(). Buffer allocation and stream startup are handled separately to allow the ALSA kernel driver to perform them at appropriate places (since the callback which starts a PCM stream is not allowed to sleep).

The intent here is to see if we have cleared the DMA_START_BIT flag. We clear it a couple lines later. The current code has a precedence bug so it is equivalent to "if (!dma_cntrl) { ...".

2012-02-09staging: r8712u: Simplify semaphoresLarry Finger
I am preparing to convert this driver from semaphore to mutex locking, The first step has been to eliminate a number of semaphores that were initialized but never used, and one whose only use was a single "up" after initialization. A total of 9 semaphores were removed in this process. One other change was to remove some inline semaphore routines that were unused. In addition, several cases had the following structure: down() if () { ... } up() The locking overhead was reduced by moving the up/down inside the if block.

2012-02-08staging: zcache: crypto API supportSeth Jennings
This patch allow zcache to use the crypto API for page compression. It replaces the direct LZO compress/decompress calls with calls into the crypto compression API. The compressor to be used is specified in the kernel boot line with the zcache parameter like: zcache=lzo or zcache=deflate. If the specified compressor can't be loaded, zcache uses lzo as the default compressor.
