Subject: [PATCH net-next 00/10] net/smc: get rid of unsafe_global_rkey

Dave,

The smc code uses the unsafe_global_rkey, exposing all memory for
remote reads and writes once a connection is established.
Here is now a patch series to get rid of unsafe_global_rkey usage.
Main idea is to switch to SG-logic and separate memory regions for RMBs.

Thanks, Ursula

Ursula Braun (10):
  net/smc: serialize connection creation in all cases
  net/smc: shorten local bufsize variables
  net/smc: introduce sg-logic for RMBs
  net/smc: use separate memory regions for RMBs
  net/smc: register RMB-related memory region
  net/smc: remove Kconfig warning
  net/smc: introduce sg-logic for send buffers
  net/smc: common functions for RMBs and send buffers
  net/smc: cleanup function __smc_buf_create()
  net/smc: synchronize buffer usage with device
