I also get the feeling that interfaces that already do this open-by-handle stuff haven't been explored either. Does anyone here know about the XFS libhandle API? This has been around for years and it does _exactly_ what these proposed syscalls are supposed to do (and more). See: http://techpubs.sgi.com/library/tpl/cgi-bin/getdoc.cgi?coll=linux&db=man&fname=/usr/share/catman/man3/open_by_handle.3.html&srch=open_by_handle For the libhandle man page. Basically: openg == path_to_handle sutoc == open_by_handle And here for the userspace code: http://oss.sgi.com/cgi-bin/cvsweb.cgi/xfs-cmds/xfsprogs/libhandle/ Cheers, Dave. -- Dave Chinner Principal Engineer SGI Australian Software Group - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
