19 lmr_handle: Handle for an instance of LMR to be destroyed.

23 The dat_lmr_free() function destroys an instance of the LMR. The LMR
24 cannot be destroyed if it is in use by an RMR. The operation does not
25 deallocate the memory region or unpin memory on a host.
26
27
28 Use of the handle of the destroyed LMR in any subsequent operation
29 except for dat_lmr_free() fails. Any DTO operation that uses the
30 destroyed LMR after the dat_lmr_free() is completed shall fail and
31 report a protection violation. The use of rmr_context of the destroyed
32 LMR by a remote peer for an RDMA DTO results in an error and broken
33 connection on which it was used. Any remote RDMA operation that uses
34 the destroyed LMR rmr_context, whose Transport-specific request arrived
35 to the local host after the dat_lmr_free() has completed, fails and
36 reports a protection violation. Remote RDMA operation that uses the
37 destroyed LMR rmr_context, whose Transport-specific request arrived to
38 the local host prior to the dat_lmr_free() returns, might or might not
39 complete successfully. If it fails, DAT_DTO_ERR_REMOTE_ACCESS is
40 reported in DAT_DTO_COMPLETION_STATUS for the remote RDMA DTO and the
41 connection is broken.
42
44 DAT_SUCCESS The operation was successful.
45
46
47 DAT_INVALID_HANDLE The lmr_handle parameter is invalid.
48
49
50 DAT_INVALID_STATE Parameter in an invalid state; LMR is in use by
51 an RMR instance.
