xfsaild 20 wakeups per second

xfsaild 20 wakeups per second

[Jason L Tibbitts III]

I was tuning the power consumption of my new laptop and noticed that
each xfsaild process is still waking up 20 times per second.  I found
http://oss.sgi.com/archives/xfs/2012-03/msg00237.html which I think
indicates that this was a workaround for some other issue and wouldn't
be permanent.  Unfortunately that was 4+ years ago.  I wasn't able to
locate any other discussion about the topic.

Was it determined that the wakeups were going to have to stay
permanently?  Or was the issue just not revisited?  And if the former,
is there a way to tune the wakeup frequency in any way?

The short answer is that the wakeups are probably going to be around for
the immediate future. There was some recent discussion on this here (see
the follow up thread to the patch):

Ah.  Sorry about bringing that back up; I just joined and I wasn't using
the right search terms to find the previous thread in the archives.

At least I now know what's happening.
