Provide a splice_read wrapper for Ceph. This does the inode shutdown check before proceeding and jumps to copy_splice_read() if the file has inline data or is a synchronous file. We try and get FILE_RD and either FILE_CACHE and/or FILE_LAZYIO caps and hold them across filemap_splice_read(). If we fail to get FILE_CACHE or FILE_LAZYIO capabilities, we use copy_splice_read() instead.
