I didn't see any pull request for cosmic (despite the development task
being set to fix committed?), so I went ahead and grabbed the commits
not already in cosmic, which were these:
net: ena: fix surprise unplug NULL dereference kernel crash
net: ena: fix driver when PAGE_SIZE == 64kB
net: ena: fix device destruction to gracefully free resources
net: ena: fix potential double ena_destroy_device()
net: ena: fix missing lock during device destruction
net: ena: fix missing calls to READ_ONCE
net: ena: fix incorrect usage of memory barriers
