Dear XFS users,


I run a Ceph cluster using XFS on Debian wheezy servers and Linux 3.10
(debian backports). I see the following line in our logs:

XFS: possible memory allocation deadlock in kmem_alloc (mode:0x250)

does this reveal a problem in my setup or may I ignore it? If it's a
problem, can someone give me any hint on solving this?
