I guess we were discussing the cases that f2fs_get_dnode_of_data won't return -ENOENT in f2fs_map_blocks but dn.blkaddr is still NULL_ADDR or NEW_ADDR ? I think I might understand the intention behind your repeated emphasis on the f2fs_map_no_dnode case? Are you saying that, on F2FS, the vast majority of sparse files fall into holes where the dnode hasn't been allocated at all, and that within the dnode the blkaddr values NULL_ADDR and NEW_ADDR—especially the latter on the read path —are relatively uncommon?
