btrfs on bcache

btrfs on bcache

[Felix Homann]

Hi,
a couple of months ago there has been some discussion about issues
when using btrfs on bcache:

http://thread.gmane.org/gmane.comp.file-systems.btrfs/31018

>From looking at the mailing list archives I cannot tell whether or not
this issue has been resolved in current kernels from either bcache's
or btrfs' side.

Can anyone tell me what's the current state of this issue? Should it
be safe to use btrfs on bcache by now?

Thanks and kind regards,
Felix

In all practicality, I don't think anyone who frequents the list knows.
 I do know that there are a number of people (myself included) who avoid
bcache in general because of having issues with seemingly random kernel
OOPSes when it is linked in (either as a module or compiled in), even
when it isn't being used.  My advice would be to just test it with some
non-essential data (maybe set up a virtual machine?).

Forwarding this to linux-bcache as well as there are two parties involved.

From looking at the mailing list archives I cannot tell whether or not
this issue has been resolved in current kernels from either bcache's
or btrfs' side.

Can anyone tell me what's the current state of this issue? Should it

The author of bcache (Kent Overstreet) has stated that it is on btrfs to 
fix the issue.
