udf: move headers out include/linux/
There's really no reason to keep udf headers in include/linux as they're not used by anything but fs/udf/. This patch merges most of include/linux/udf_fs_i.h into fs/udf/udf_i.h, include/linux/udf_fs_sb.h into fs/udf/udf_sb.h and include/linux/udf_fs.h into fs/udf/udfdecl.h. The only thing remaining in include/linux/ is a stub of udf_fs_i.h defining the four user-visible udf ioctls. It's also moved from unifdef-y to headers-y because it can be included unconditionally now. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jan Kara <jack@suse.cz>
