Bug Description
The attached script creates an ecryptfs volume, and then an overlay FS using it (and an ordinary directory) as inferiors. Reading from a file in the overlay causes a kernel oops.
Reproduction:
Run the enclosed script sudo root
Details:
Fresh xubuntu 19.04 amd64 (in VirtualBox VM) on Ryzen; same error occurs on ubuntu 19.04 on unvirtualised Intel-x86-64.
