Hi Miklos,

Compilation of virtio-fs as module fails. While it works if compiled as
non-module.

fs/fuse/virtio_fs.c: In function ‘copy_args_to_argbuf’:
fs/fuse/virtio_fs.c:255:5: error: ‘struct fuse_req’ has no member named ‘argbuf’
  req->argbuf = kmalloc(len, GFP_ATOMIC);

It can't find req->argbuf. 

I noticed that you have put ifdef around argbuf.

#ifdef CONFIG_VIRTIO_FS
        /** virtio-fs's physically contiguous buffer for in and out args */
        void *argbuf;
#endif

It should have worked. Not sure why it is not working.

Vivek
