Hi, this is a part of the previous RFC patchset, and it's preliminary for eliminating set_fs() usages in the rest ALSA codes. This patchset itself converts the existing copy and silence PCM ops to a new single copy_silence ops. The new callback takes in_kernel flag for allowing in-kernel buffer copy, so that the PCM drivers can pass the buffer in kernel-space later directly without set_fs() hackery. The latest codes are found in topic/kill-set_fs branch of sound git tree. The media people are Cc'ed for solo6x10 changes.
