[Qemu-devel] [RFC PATCH v2 19/35] multi-process: store info about the remote process |
Date: |

From: Elena Ufimtseva <address@hidden>
Store info about the remote process in a hash table, so that
it could be used later for QMP/HMP commands.

Changes in v2:
- moved the “remote_devs” object from “pcms” (PCMachineState)
to “ms” (MachineState).
