25 * @date May 2013
26 * @brief Samba VFS module for glusterfs
27 *
28 * @todo
29 * - AIO support\n
30 * See, for example \c vfs_aio_linux.c in the \c sourc3/modules directory
31 * - sendfile/recvfile support
32 *
33 * A Samba VFS module for GlusterFS, based on Gluster's libgfapi.
34 * This is a "bottom" vfs module (not something to be stacked on top of
35 * another module), and translates (most) calls to the closest actions
36 * available in libgfapi.
