Absolutely. Except it's 3.11 material and I can only usefully create a -next branch once -rc1 is out. > I have some other cleanups which are on hold for the moment pending > MST's vhost_net simplification. MST, how's that going? Not too well. The array of status bytes which was designed to complete packets in order turns out to be a very efficient datastructure: It gives us a way to signal completions that is completely lockless for multiple completers, and using the producer/consumer model saves extra scans for the common case. Overall I can save some memory and clean up some code but can't get rid of the producer/consumer idices (currently named upend/done indices) which is what you asked me to do. Your cleanups basically don't work with zcopy because they ignore the upend/done indices? Would you like to post them, noting they only work with zcopy off, and we'll look for a way to apply them, together? > Thanks, > Rusty. _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
