[alsa-devel] [PATCH 00/16] ALSA: Convert to new copy_silence PCM ops

[Takashi Iwai]

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.
