Re: [Linux-streams] Still doesn't work

[Jared Riley]

Hi,

I have gone back to 2.14.13 so that I could see what would happen. I successfully ran overnight with no problems. I had some problems with race conditions on open, however since I think that was the point of the latest set of fixes I'm not too concerned with that.

You may recall that I was originally complaining about 2 things. One was the machine deadlocks which have received some discussion on this list.

The second problem that I had was my test application hangs in lis_sleep_on_wwrite. I am fairly sure that there is a race condition between this and lis_wake_up_all_wwrite. To test this, I changed the high and low water marks of my driver. In my original testing, they were set to 3 messages and 2 messages respectively. Changing to 8 messages and 2 messages seems to have solved my problem, or at least avoided it.

Jared
