26 * @brief Samba VFS module for glusterfs
27 *
28 * @todo
29 * - sendfile/recvfile support
30 *
31 * A Samba VFS module for GlusterFS, based on Gluster's libgfapi.
32 * This is a "bottom" vfs module (not something to be stacked on top of
33 * another module), and translates (most) calls to the closest actions
34 * available in libgfapi.
