CIFSD is an open-source in-kernel CIFS/SMB server created by Namjae Jeon for the Linux kernel. Initially the goal is to provide improved file I/O performance, but the bigger goal is to have some new features which are much easier to develop and maintain inside the kernel and expose the layers fully. Directions can be attributed to sections where Samba is moving to a few modules inside the kernel to have features like Remote direct memory access (RDMA) to work with actual performance gain.
