I didn't try that. I've tried 4 patches from Paul's linux-rcu tree. I can try another portion of patches, no problem :)Replacing cond_resched_rcu_qs in shrink_node_memcg by cond_resched would be really helpful to tell whether we are missing a real scheduling point or whether something more serious is going on here.
Ok, I'll try that. -- Boris Zhmurov System/Network Administrator mailto: bb@kernelpanic.ru "wget http://kernelpanic.ru/bb_public_key.pgp -O - | gpg --import" -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
