The next list_for_each_entry_continue() from\nthe hitch finds the same resource again, causing an infinite loop.\n\nFix by deferring del_bulk_move to the success path only.\n\nOn the success path, TTM_TT_FLAG_SWAPPED has just been set by\nttm_tt_swapout() but the resource is still tracked in the bulk_move range,\nso ttm_resource_del_bulk_move()'s !ttm_resource_unevictable() guard would\nincorrectly skip the removal.
