From: Aleksandar Markovic <amarkovic@wavecomp.com>

Both FS_IOC_FSGETXATTR and FS_IOC_FSSETXATTR accept a pointer to
the structure

struct fsxattr {
    __u32         fsx_xflags;     /* xflags field value (get/set) */
    __u32         fsx_extsize;    /* extsize field value (get/set)*/
    __u32         fsx_nextents;   /* nextents field value (get)	*/
    __u32         fsx_projid;     /* project identifier (get/set) */
    __u32         fsx_cowextsize; /* CoW extsize field value (get/set)*/
    unsigned char fsx_pad[8];
};

as their third argument.

These ioctls were relatively recently introduced, so the "#ifdef"
guards are used in this implementation.
