+AD4 +AD4 Hi Nick and Nathan,
+AD4 +AD4 
+AD4 +AD4 Had you noticed the following e-mail from early October:
+AD4 +AD4 https://marc.info/?l+AD0-linux-kernel+ACY-m+AD0-153849955503249?
+AD4 
+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:
+AD4 https://lkml.org/lkml/2018/10/27/3
+AD4 https://lkml.org/lkml/2018/10/27/44

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?

Bart.
