Seems like no one is going to pick up the glove

Think I'll give a shot to Nick's lockless pagecache patch

Just for fun

Do you use Reiser4? If so, any problems?

Thanks for the updated kernel patch. I gave it a whirl. Unfortunately I still run into the exact same reiser4 kernel panic as I had before. Very strange. Anything I can do to help figure it out though, I'm game.

So I was wondering, is this supposed to be the actual lockless/reiser4 fix?

If so, I don't actually see this being applied in the patchset to remove the reiser4 problem, but then again I'm really not sure what I'm doing in this area. I do, of course, have a backup and all, but I should probably just sit tight until I get more input. Thanks for looking into this.

I just don't think reiser4 and lockless are going to work together.

Yeah, sounds like it, at least for now. I haven't been able to dig up much more information on the problem. The one thing I find odd though, is that the kernel panic occurs no matter what scheduler I choose. Shouldn't the lockless/reiser stuff only mess up with the anticipatory scheduler? Could that mean that there is actually some other issue that I'm running into? Well no matter, I'll sit tight and see if a few more people hopefully give it a try and maybe try to get it onto one of my other non-reiser machines. Hopefully the two pieces of code aren't so incompatible that they can't eventually coexist.

Fixed reiser4, expect a new release within the next day or so.
