Hi MST, I see that a new feature, VHOST_USER_PROTOCOL_F_INBAND_NOTIFICATIONS (https://git.qemu.org/?p=qemu.git;a=blob;f=docs/interop/vhost-user.rst;h=3b1b6602c77932101e1e3b098e35c2497f5b0260;hb=HEAD#l817), and corresponding VHOST_USER_VRING_KICK (https://git.qemu.org/?p=qemu.git;a=blob;f=docs/interop/vhost-user.rst;h=3b1b6602c77932101e1e3b098e35c2497f5b0260;hb=HEAD#l1252) message has been added to the documentation for the vhost-user protocol and seem to be added in libvhost-user. However I don’t see the feature or message number reserved in the core vhost-user code (https://git.qemu.org/?p=qemu.git;a=blob;f=hw/virtio/vhost-user.c;h=08e7e63790e5bcfae6cd31bf9ccd32c3a7347f4e;hb=HEAD#l47)
I understand these features are mostly for simulation, but surely the numbers for these features should at least be reserved as more features and messages are frequently being added. Is this an oversight? With the aim of preventing future confusion should I send a patch to add them in /hw/virtio/vhost-user.c? Thanks, Raphael
