Hi, this is a sort of RFC, a revised patchset of the previous two patches for killing set_fs() usages in PCM. Instead of converting to the merged copy_silence ops, this adds a new copy_kernel ops instead. At the same time, copy/silence are changed to receive the position and size in bytes instead of frames. This allows us to simplify the PCM core code. As a result, a good amount of code could be removed from pcm_lib.c. Note that this patchset isn't complete, containing only two driver conversions (nm256 for interleaved and rme9652 for non-interleaved) as a demonstration.
