+ * the buffer creator / user. This latter happens, for example, at eviction.

+ * @persistant_swap_storage: Usually the swap storage is deleted for buffers
+ * pinned in physical memory. If this behaviour is not desired, this member
+ * holds a pointer to a persistant shmem object.
+ * @ttm: TTM structure holding system pages.

+ * @val_seq: Sequence of the validation holding the @reserved lock.
+ * Used to avoid starvation when many processes compete to validate the
+ * buffer. This member is protected by the bo_device::lru_lock.
+ * @seq_valid: The value of @val_seq is valid. This value is protected by
+ * the bo_device::lru_lock.
+ * @reserved: Deadlock-free lock used for synchronization state transitions.
+ * @sync_obj_arg: Opaque argument to synchronization object function.

+ * depending on the memory type. For SYSTEM type memory, it should be 0.
+ * @cur_placement: Hint of current placement.
+ *
+ * Base class for TTM buffer object, that deals with data placement and CPU
+ * mappings. GPU mappings are really up to the driver, but for simpler GPUs
+ * the driver can usually use the placement offset @offset directly as the

+ * Locks a buffer object for validation. (Or prevents other processes from
+ * locking it for validation) and removes it from lru lists, while taking
+ * a number of measures to prevent deadlocks.
+ *
+ * Deadlocks may occur when two processes try to reserve multiple buffers in
+ * different order, either by will or as a result of a buffer being evicted
+ * to make room for a buffer already reserved. (Buffers are reserved before
+ * they are evicted). The following algorithm prevents such deadlocks from
+ * occuring:
+ * 1) Buffers are reserved with the lru spinlock held. Upon successful
+ * reservation they are removed from the lru list. This stops a reserved buffer
+ * from being evicted. However the lru spinlock is released between the time
+ * a buffer is selected for eviction and the time it is reserved.
+ * Therefore a check is made when a buffer is reserved for eviction, that it
+ * is still the first buffer in the lru list, before it is removed from the
+ * list. @check_lru == 1 forces this check. If it fails, the function returns
+ * -EINVAL, and the caller should then choose a new buffer to evict and repeat
+ * the procedure.
+ * 2) Processes attempting to reserve multiple buffers other than for eviction,
+ * (typically execbuf), should first obtain a unique 32-bit
+ * validation sequence number,
+ * and call this function with @use_sequence == 1 and @sequence == the unique
+ * sequence number. If upon call of this function, the buffer object is already
+ * reserved, the validation sequence is checked against the validation
+ * sequence of the process currently reserving the buffer,
+ * and if the current validation sequence is greater than that of the process
+ * holding the reservation, the function returns -EAGAIN. Otherwise it sleeps
+ * waiting for the buffer to become unreserved, after which it retries
+ * reserving.
+ * The caller should, when receiving an -EAGAIN error
+ * release all its buffer reservations, wait for @bo to become unreserved, and
+ * then rerun the validation with the same validation sequence. This procedure
+ * will always guarantee that the process with the lowest validation sequence
+ * will eventually succeed, preventing both deadlocks and starvation.
+ *
+ * Returns:
+ * -EAGAIN: The reservation may cause a deadlock.
+ * Release all buffer reservations, wait for @bo to become unreserved and
+ * try again. (only if use_sequence == 1).
+ * -ERESTART: A wait for the buffer to become unreserved was interrupted by
+ * a signal. Release all buffer reservations and return to user-space.
