To prevent deadlock, bios in the hold list should be flushed before dm_rh_stop_recovery() is called in mirror_suspend(). The recovery can't start because there are pending bios and therefore dm_rh_stop_recovery deadlocks. When there are pending bios in the hold list, the recovery waits for the completion of the bios after recovery_count is acquired. The recovery_count is released when the recovery finished, however, the bios in the hold list are processed after dm_rh_stop_recovery() in mirror_presuspend(). dm_rh_stop_recovery() also acquires recovery_count, then deadlock occurs.
