Jason Gunthorpe ef3642c4f5 RDMA/mlx5: Fix error unwinds for rereg_mr ... This is all a giant train wreck of error handling, in many cases the MR is left in some corrupted state where continuing on is going to lead to chaos, or various unwinds/order is missed. rereg had three possible completely different actions, depending on flags and various details about the MR. Split the three actions into three functions, and call the right action from the start. For each action carefully design the error handling to fit the action: - UMR access/PD update is a simple UMR, if it fails the MR isn't changed, so do nothing - PAS update over UMR is multiple UMR operations. To keep everything sane revoke access to the MKey while it is being changed and restore it once the MR is correct. - Recreating the mkey should completely build a parallel MR with a fully loaded PAS then swap and destroy the old one. If it fails the original should be left untouched. This is handled in the core code. Directly call the normal MR creation functions, possibly re-using the existing umem. Add support for working with ODP MRs. The READ/WRITE access flags can be changed by UMR and we can trivially convert to/from ODP MRs using the logic to build a completely new MR. This new logic also fixes various problems with MRs continuing to work while their PAS lists are no longer valid, eg during a page size change.
