Dear David, I have seen that you have made some recent changes in netfs now visible in linux-next. In commit 62c3b7481b9a ("netfs: Provide a writepages implementation"), you have added some code that is included under #ifdef CONFIG_NETFS_FSCACHE, but if I read the code correctly, the actual intended config here is called CONFIG_FSCACHE. As I am not 100% sure and this code just appeared on linux-next, I thought I would just write you a mail rather than sending a one-line RFC patch. Best regards, Lukas
