Just gave it a try, jffs2 does not mount anymore. The problem is that you define
an Opt_source in super.c, but never evaluate it -> jffs2_parse_param() returns
-EINVAL.

What I really don't get is the new logging stuff in include/linux/fs_context.h.
printk() is already an overloaded beat, why another layer?

The log output seems very odd to me:
[   13.117593] e MTD: Couldn't look up '/dev/mtd0': -15

Please notice the "e" before MTD, first I though this is a memory
corruption, but is your log level?!

Thanks,
