we wait for all devices to finish their +probing before we try to mount the rootfs. +In practice, this means that we end up waiting 2 extra seconds for +the PS/2 mouse probing even though the root holding device has been +ready since a long time. + +The previous two patches in this series made the RAID autodetect code +do it's own "wait for probing to be done" code, and added +"wait and retry" functionality in case the root device isn't actually +available. + +These two changes should make it safe to remove the delay itself, +and this patch does this.

This member is ++ * used to avoid destruction while the buffer object is still on a list. ++ * Lru lists may keep one refcount, the delayed delete list, and kref != 0 ++ * keeps one refcount. When this refcount reaches zero, ++ * the object is destroyed. ++ * @proposed_flags: Proposed placement for the buffer. Changed only by the ++ * creator prior to validation as opposed to bo->mem.proposed_flags which is ++ * changed by the implementation prior to a buffer move if it wants to outsmart ++ * the buffer creator / user. This latter happens, for example, at eviction. ++ * @buffer_start: The virtual user-space start address of ttm_bo_type_user ++ * buffers. ++ * @type: The bo type. ++ * @offset: The current GPU offset, which can have different meanings ++ * depending on the memory type. For SYSTEM type memory, it should be 0. ++ * @mem: structure describing current placement. ++ * @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. ++ * @lru: List head for the lru list. ++ * @ddestroy: List head for the delayed destroy list. ++ * @swap: List head for swap LRU list. ++ * @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. ++ * @destroy: Destruction function. If NULL, kfree is used. ++ * @sync_obj_arg: Opaque argument to synchronization object function. ++ * @sync_obj: Pointer to a synchronization object. ++ * @priv_flags: Flags describing buffer object internal state. ++ * @event_queue: Queue for processes waiting on buffer object status change. ++ * @mutex: Lock protecting all members with the exception of constant members ++ * and list heads. We should really use a spinlock here. ++ * @num_pages: Actual number of pages. ++ * @ttm: TTM structure holding system pages. ++ * @vm_hash: Hash item for fast address space lookup. Need to change to a ++ * rb-tree node. ++ * @vm_node: Address space manager node. ++ * @addr_space_offset: Address space offset. ++ * @cpu_writes: For synchronization. Number of cpu writers. ++ * @reserved: Deadlock-free lock used for synchronization state transitions. ++ * @acc_size: Accounted size for this object. ++ * ++ * 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 ++ * GPU virtual address. For drivers implementing multiple ++ * GPU memory manager contexts, the driver should manage the address space ++ * in these contexts separately and use these objects to get the correct ++ * placement and caching for these GPU maps. This makes it possible to use ++ * these objects for even quite elaborate memory management schemes. ++ * The destroy member, the API visibility of this object makes it possible ++ * to derive driver specific types. ++ */ ++ ++struct ttm_buffer_object { ++ struct ttm_bo_device *bdev; ++ struct kref kref; ++ struct kref list_kref; ++ ++ /* ++ * If there is a possibility that the usage variable is zero, ++ * then dev->struct_mutex should be locked before incrementing it. ++ */ ++ ++ uint32_t proposed_flags; ++ unsigned long buffer_start; ++ enum ttm_bo_type type; ++ unsigned long offset; ++ struct ttm_mem_reg mem; ++ uint32_t val_seq; ++ bool seq_valid; ++ ++ struct list_head lru; ++ struct list_head ddestroy; ++ struct list_head swap; ++ ++ struct file *persistant_swap_storage; ++ ++ void (*destroy) (struct ttm_buffer_object *); ++ ++ void *sync_obj_arg; ++ void *sync_obj; ++ ++ uint32_t priv_flags; ++ wait_queue_head_t event_queue; ++ struct mutex mutex; ++ unsigned long num_pages; ++ ++ struct ttm_tt *ttm; ++ struct rb_node vm_rb; ++ struct drm_mm_node *vm_node; ++ uint64_t addr_space_offset; ++ ++ atomic_t cpu_writers; ++ atomic_t reserved; ++ ++ size_t acc_size; ++}; ++ ++/** ++ * struct ttm_bo_kmap_obj ++ * ++ * @virtual: The current kernel virtual address. ++ * @page: The page when kmap'ing a single page. ++ * @bo_kmap_type: Type of bo_kmap. ++ * ++ * Object describing a kernel mapping.

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.

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.
