  • async_disconnecting is used to check if waiting is needed.

  • No need to call session_put() in rm_remote_free().
    Because at this moment, maybe some other requests are still in progress.

Problem Statement

While doing Motr shutdown, there might be panic like this:

=== pids of services: 2106389 2106891 2106965 2107036 2107045 2107047 2107058 ===
Shutting down services one by one. mdservice is the last.

Motr pid 2106389 waits for debugger.

The problem is that the reverse session connection has been already destroyed and freed.

Design

There are two fixes in this patch.

  1. No need to call session_put() in rm_remote_free().
    Because at this moment, maybe some other RM requests are still in progress. The reverse connection will be destroyed in
    m0_rpc_service_reverse_sessions_cleanup() while doing system finalization.
  2. Adding a flag rlk_async_disconnecting in the rpc_link. This will avoid making duplicated calls if a
    m0_rpc_service_reverse_session_put() is already in progress. And this flag is also used to check if a wait is needed.
