andrew, this is really helpful. should we conclude that until some announcement from reiser that they have addressed this, the reiserfs should be avoided on low latency systems?
It seems that way, yes. I do not know how common the holdoffs are in real life. It would be interesting if there was a user report that switching from reiserfs to ext2/ext3 actually made a difference - this would tell us that it is indeed a real-world problem.
Note that this info because available because someone set /proc/asound/*/*/xrun_debug. We need more people doing that
Can I just point out that the reiserfs3.6 delays that I originally reported with the preempt threshhold test did not come up once the patch was fixed. I have my preempt threshold set at 1ms and did not see one single reiserfs dump in my syslog. ie I don't think I am personally seeing any significant reiserfs3.6 latencies.
Cheers, Con
