Re: ext4_file_open: Inconsistent encryption contexts (commit ff978b09f973) breaking Docker

From: Daniel Axtens
Date: Mon Mar 14 2016 - 02:47:33 EST

Hi all,

To make sure I wasn't crazy, I installed a mainline kernel on my x86 laptop.

It also doesn't work there, but I do get a far more detailed set of
backtraces, which I've added below. It also means it's not powerpc
specific, which should help in debugging it.

Regards,
Daniel
