If we fail 221a07ce53Spooka readdir itself, it's treated as success 231a07ce53Spooka 241a07ce53Spooka * implement file system layering .. this will most likely bring 251a07ce53Spooka massive changes to how the ops vector is handled, for instance. 261a07ce53Spooka pcc/pu division should stay quite like the way it is now, but 271a07ce53Spooka maybe there will be layer specific ops. 281a07ce53Spooka 291a07ce53Spooka * make puffs more like kernel vfs - or make kernel vfs more like puffs 301a07ce53Spooka 311a07ce53Spooka * decide what to do about setback operations. they kind of violate 32*638ce789Spooka the transparency of FAF for op handling 33*638ce789Spooka 34*638ce789Spooka * remove flags parameter to puffs_init and replace with something 35*638ce789Spooka more generic 361a07ce53Spooka 371a07ce53Spooka * fix incoming requests to not require memcpy with continuations 381a07ce53Spooka (not user-visible?) 391a07ce53Spooka 401a07ce53Spooka * make continuations play with libpthread, lib/36011 (not user-visible?) 411a07ce53Spooka 421a07ce53Spooka * clean up the request dispatching / continuation code (not user-visible?) 43
