Linux next version 20190204 boot failed on all arm and arm64 devices and qemu. Kernel crash log not available from the console.

No kernel log on - Hikey, db410c and qemu_arm64. Kernel log available on Juno but it is not a crash log.

I haven't got further than I think it is commit 6b019dde87bc ("vfs: Implement a filesystem superblock creation/configuration context")

hmm, it can't be only this patch. since i think it landed in next-20190130.

Cheers, Anders

that introduced it, from the oops I got when I tested it locally:
