[PATCH 0/5] ALSA: seq: Optimization with RCU

Posted by Takashi Iwai 1 month, 2 weeks ago

Hi,

here are a set of (rather small) patches for optimizing lockings in
ALSA sequencer core by replacing with RCU.  Most of changes are
straight-forward conversions from read-lock to RCU, or a simple
pointer assignment.
