Well, it's "copy data". The point here was in-place-concatenation (with the deletion/removal of the file-to-be-tucked-on implied). sendfile() doesn't do that. It only manipulates metadata, and should be able to do that "instantly" if possible. Just move - with no (intermediate) data duplication along the way. Although one could now start speculating about using copy-on-write techniques to implement "instant sendfile" within a filesystem via concatenation (i.e. make sendfile == "snapshot file"+"concat file"). Ok, I'll stop it here. Too much pure speculation. FrankH. _______________________________________________ ufs-discuss mailing list [email protected]
