[Bug 1823805] Re: The 4.18.0-1015.15 Azure Kernel Panics Due to Missing Commit
And looking a little further, commit ae6935ed7d42(Bionic commit
c40598d9e67c) was added per bug 1812123 for DPDK. In that bug, we
requested two commits:
b5679cebf780 ("vmbus: fix subchannel removal")
5e3c420dcca5 ("uio_hv_generic: set callbacks on open")
However, commit b5679cebf780 is a fix for commit ae6935ed7d42, so commit
ae6935ed7d42 was also included. That then led to this bug, because with
commit ae6935ed7d42, commit c967590457ca is now also needed.
