Let us know how you get on :) sorry for late response. (I didn't notice your mail ;-) You are right... stupid user space caching is very important problem. but I think this is no libc problem. glibc malloc hardly caches the memory. (its default behavior only caching 128K.) but some application use large memory for too opportunistic caching. I understood we need propagandize that using mem_notify to application guys after it merge mainline. I have no idea of solve it easily. - 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
