  - Fix code style suggested by Manos Pitsidianakis
- [PATCH 4/5] vhost-user-scsi: start vhost when guest kicks
  - Use 'DEVICE()' macro in vhost_user_scsi_handle_output to replace the
    'parent_obj.parent_obj.parent_obj.parent_obj'.

Changes for v7:
- [PATCH 3/5] vhost-user-scsi: support reconnect to backend
  - Add reporting the error in vhost-scsi;
  - Rebase to master and fix the conflict.
- Add "Reviewed-by" tags.

Changes for v6:
- [PATCH] vhost-user: fix lost reconnect
  - Fix missing assign event_cb.

Changes for v5:

- Merge
  https://lore.kernel.org/all/20230830045722.611224-1-fengli@smartx.com/ to
  this series.
- Add ERRP_GUARD in vhost_user_scsi_realize;
- Reword the commit messages.

Changes for v3:
- Split the vhost_user_scsi_handle_output to a separate patch;
- Move the started_vu from vhost scsi common header to vhost-user-scsi header;
- Fix a log print error;

Changes for v2:
- Split the v1 patch to small separate patchset;
- New patch for fixing fd leak, which has sent to reviewers in another
  mail;
- Implement the `vhost_user_scsi_handle_output`;
- Add the started_vu safe check;
- Fix error handler;
- Check the inflight before set/get inflight fd.

Li Feng (5):
  vhost-user-common: send get_inflight_fd once
  vhost: move and rename the conn retry times
  vhost-user-scsi: support reconnect to backend
  vhost-user-scsi: start vhost when guest kicks
  vhost-user: fix lost reconnect
