Hi Steve, The following patch enables fscache even for scenarios where files are opened in rw mode. Our current implementation only enables fscache when the file is opened O_RDONLY. https://github.com/sprasad-microsoft/smb3-kernel-client/pull/5 Note that this patch can safely be backported. It still does not use netfs helper library. I'll be sending another patch with the netfs helper integration soon. -- Regards, Shyam
