It's an awful lot of maintenance on what looks to be a esoteric (at
best) code path.
It's never chosen by falling back to that mode.
physical has long been on the chopping block. Last time
I suggested removing it I got a complaint. But there's no
in-kernel device that requires this mode, so seems like
it should go sooner rather than later.
I'm planning to add support for NFS/RDMA with Kerberos
in v4.8. That seems like a very appropriate time to
remove PHYSICAL, which is not secure.
Is there any objection to removing PHYSICAL in v4.8?
Please do :)
