This series removes the support for FMR mode to register memory. This ancient mode is unsafe and not maintained/tested in the last few years. It also doesn't have any reasonable advantage over other memory registration methods such as FRWR (that is implemented in all the recent RDMA adapters). This series should be reviewed and approved by the maintainer of the effected drivers and I suggest to test it as well. The tests that I made for this series (fio benchmarks and fio verify data): 1. iSER initiator on ConnectX-4 2. iSER initiator on ConnectX-3 3. SRP initiator on ConnectX-4 (loopback to SRP target) 4. SRP initiator on ConnectX-3 Not tested: 1. RDS 2. mthca 3. rdmavt
This will effectively kill qib which uses rdmavt. It's gonna have to be a NAK from me.
