Abstract: Embodiments of the present invention disclose a method and an apparatuses for querying for and traversing a virtual memory area. The method includes: determining whether a virtual memory area (vma) corresponding to a query address is in an adjacent range of a cached vma, and if the vma corresponding to the query address is in the adjacent range of the cached vma, querying for the vma by using a thread on a node of a threaded red-black tree. Since an adjacent range of the cached vma can always be determined, the hit rate of accessing the cache is improved, and the time complexity of implementing the whole vma traversal is O(n), thereby improving vma query efficiency.

Abstract: An earphone assembly includes an earphone and the earphone case, where the earphone has a first magnetic piece, and the earphone case includes a case body and a lid. The case body is provided with an accommodating slot configured to accommodate the earphone, and the lid is configured to open or close the case body. A second magnetic piece is disposed on the lid and is magnetically attached to the first magnetic piece. When the lid is lifted to open the case body, the earphone moves with the lid and is detached from the accommodating slot. When the lid is closed to close the case body, the earphone is attached to the lid and moves with the lid until the earphone is accommodated in the accommodating slot.

Abstract: This application discloses a container access method and apparatus. The method includes: receiving a container access request, which is used to request to access a target container; selecting a driver instance corresponding to the target container from multiple currently-running driver instances, where different driver instances in the multiple driver instances are used to drive different types of containers, and the multiple driver instances are managed by using a same program; and sending the container access request to the selected driver instance. In this solution, one program manages driver instances that are used to drive different types of containers, so that a user can access multiple containers of different types by using one program. This reduces running overheads of a program that manages multiple driver instances in a container engine.
