    Subject[PATCH 5.16 0082/1039] drm/ttm: Put BO in its memory managers lru list
    Date
    From: xinhui pan <xinhui.pan@amd.com>

    commit 781050b0a3164934857c300bb0bc291e38c26b6f upstream.

    After we move BO to a new memory region, we should put it to
    the new memory manager's lru list regardless we unlock the resv or not.
