Yes, apparently shm swapping is very sensible to balancing issues. It behaves very differently with different patch levels without ever changing the shm_swap function. We should really work on integrating it into the page cache...

Since I changed absolutely nothing to the shm_swap() functions, I guess this means that sometimes shm_swap() is not called by the system even when it should have been. (at least, this is what a debugging test by one of the other testers suggests) I will look into this and come up with a fix. regards, Rik -- "What you're running that piece of shit Gnome?!?!" -- Miguel de Icaza, UKUUG 2000 http://www.conectiva.com/ http://www.surriel.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
