Btrfs devel - Apr 2014 - RE: Can anyone boot a system using btrfs root with linux 3.14 or newer? - RESOLVED

The problem reported in this thread has been RESOLVED.

It's not BTRFS's fault.

Debugging on my part led to the actual problem in do_mounts.c - some filesystems
mount routines return error codes other than 0, EACCES and EINVAL and such
return codes result in the kernel panicking without trying to mount root with
all of the available filesystems.

Patch is available as attachment to bug 74901 -
https://bugzilla.kernel.org/show_bug.cgi?id=74901 . The bugentry documents how I
managed to find the problem.

Also, the patch has been sent to the linux kernel mailing list - see
http://news.gmane.org/find-root.php?group=gmane.linux.kernel&article=1691881
Hopefully, it will find its way into the kernel, and later on - in stable
releases.

Thanks to you all!
