There is no enforced memory order between setting\nthe host into error recovery state and counting busy commands. This can\nresult in a race with scsi_dec_host_busy where neither CPU sees both\nconditions of all commands inactive and the host error state to request\nwaking the error handler.\n\nTo fix this, run the scsi_schedule_eh's scsi_eh_wakeup from a new work item\nwhich will use rcu to ensure scsi_schedule_eh's call to scsi_host_busy will\noccur after the error state is globally visible and will be seen by any\ncurrent scsi_dec_host_busy callers."
