  checkpatch: g_test_message does not need a trailing newline
  vl.c: remove outdated comment
  vhost-user-bridge: fix recvmsg iovlen
  vl: Improve error message when we can't load fw_cfg from file
  vmstate: constify VMStateField
  migration: savevm: consult migration blockers
  lsi: Reselection needed to remove pending commands from queue
