Hmm, I think I still prefer an ioctl to switch modes. It makes for cleaner separation of control and data path. > To make the interface more future-proof, we can > ask all new-ABI users to use pwrite with offset 0, > and validate the offset in kernel. > Is this a good idea? No, I don't like that interface. Especially the converse interface of pread() at offset 0 seems very confusing. - R. _______________________________________________ general mailing list general@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
