-/**
- * ttm_bo_init
- *
- * @bdev: Pointer to a ttm_device struct.
- * @bo: Pointer to a ttm_buffer_object to be initialized.
- * @size: Requested size of buffer object.
- * @type: Requested type of buffer object.
- * @placement: Initial placement for buffer object.
- * @page_alignment: Data alignment in pages.
- * @interruptible: If needing to sleep to wait for GPU resources,
- * sleep interruptible.
- * pinned in physical memory. If this behaviour is not desired, this member
- * holds a pointer to a persistent shmem object. Typically, this would
- * point to the shmem object backing a GEM object if TTM is used to back a
- * GEM user interface.
- * @sg: Scatter-gather table.
- * @resv: Pointer to a dma_resv, or NULL to let ttm allocate one.
- * @destroy: Destroy function. Use NULL for kfree().
- *
- * This function initializes a pre-allocated struct ttm_buffer_object.
- * As this object may be part of a larger structure, this function,
- * together with the @destroy function,
- * enables driver-specific objects derived from a ttm_buffer_object.
- *
- * On successful return, the caller owns an object kref to @bo. The kref and
- * list_kref are usually set to 1, but note that in some situations, other
- * tasks may already be holding references to @bo as well.
- *
- * If a failure occurs, the function will call the @destroy function, or
- * kfree() if @destroy is NULL. Thus, after a failure, dereferencing @bo is
- * illegal and will likely cause memory corruption.
- *
- * Returns
- * -ENOMEM: Out of memory.
- * -EINVAL: Invalid placement flags.
- * -ERESTARTSYS: Interrupted by signal while sleeping waiting for resources.
