It seems to me that you are talking about only cases where memory allocation functions return NULL instead of waiting forever. But that is an optimistic assumption. What I'm observing under extreme memory pressure with XFS ( https://lkml.org/lkml/2014/7/2/249 ) is that memory allocation functions spin forever while keeping some of kernel threads locked. Do you have ideas for solving (or at least detecting) this behavior? -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
