[alsa-devel] [PATCH RFC 05/21] ALSA: pcm: enable parameter tracepoints at CONFIG_SND_DEBUG only

[Takashi Sakamoto]

In a previous commit, tracepoints are added for PCM parameter processing.
As long as I know, this implementation increases size of relocatable
object by 135%. For vendors who are conscious of memory footprint, it
brings apparent disadvantage.

This commit uses CONFIG_SND_DEBUG option to enable/disable the
tracepoints.
