Subject: Bug - bcache: "unable to handle kernel NULL pointer dereference" when trying to add a md caching device
Date: Thu, 24 Mar 2016 16:19:39 +0100	[thread overview]
Message-ID: <56F4058B.1030309@roesner-online.de> (raw)

Hell,

I experienced a bug after upgrading to a recent kernel (4.5.0).

# echo /dev/md2 > /sys/fs/bcache/register

gives me a stack trace.

I created a bug in the kernel bugtracker but I'm not sure if it has been
noticed by the bcache developers:

<https://bugzilla.kernel.org/show_bug.cgi?id=114871>

Could somebody have a look?

Cheers
Sebastian
