Amir Goldstein 9e46b840c7 ovl: support stacked SEEK_HOLE/SEEK_DATA ... Overlay file f_pos is the master copy that is preserved through copy up and modified on read/write, but only real fs knows how to SEEK_HOLE/SEEK_DATA and real fs may impose limitations that are more strict than ->s_maxbytes for specific files, so we use the real file to perform seeks. We do not call real fs for SEEK_CUR:0 query and for SEEK_SET:0 requests.
