+AD4 +AD4 Hi Nick and Nathan,
+AD4 +AD4 
+AD4 +AD4 Had you noticed the following e-mail from early October:

+AD4 From this subthread with Linus, removal of the exofs fs and scsi osd
+AD4 code would be a user visible change and is not an option. See:

Hi Nick,

Linus wrote that removing a filesystem is considered a userspace breakage
if a user notices. The key part is +ACI-if a user notices+ACI. Who are the exofs
users?
