Disco only needs 37c2578c0c40. Cosmic does not require any dependent commits, just the two above(37c2578c0c40, e04e7a7bbd4b). linux-azure and Bionic(4.15+ kernels) require the following five dependent commits: 4.18-rc1 - 7bf7bb37f16a ("hv_netvsc: fix network namespace issues with VF support") 4.18-rc4 - 3ffe64f1a641 ("hv_netvsc: split sub-channel setup into async and sync") 4.19-rc1 - 50229128727f ("Drivers: hv: vmbus: Fix the offer_in_progress in vmbus_process_offer()") 4.19-rc3 - e04e7a7bbd4b ("hv_netvsc: Fix a deadlock by getting rtnl lock earlier in netvsc_probe()") 4.19-rc4 - 6712cc9c2211 ("vmbus: don't return values for uninitalized channels") == Fixes == ("Dependent commits mentioned above, based on Ubuntu release") e04e7a7bbd4b ("hv_netvsc: Fix a deadlock by getting rtnl lock earlier in netvsc_probe()") 37c2578c0c40 ("Drivers: hv: vmbus: Offload the handling of channels to two workqueues") == Regression Potential == Low.
