Abstract: Systems, methods, and computer program products for target memory pressure event notifications are disclosed. Processes running on a device can register to receive memory pressure event notifications from a memory management system, which are sent while memory pages are being reclaimed. Active processes running on a device processor can be assigned a priority that ranges from low to high. Responsive to a memory pressure event occurring on the device, the memory management system determines whether less than a threshold number of high priority processes are active on the device. If so, the memory management system sends a memory pressure event notification to the registered process with the lowest priority among the active processes.

Abstract: Systems and methods are disclosed for implementing an educational mode on a portable computing device, such as a tablet computer, that is a single-user system, used serially by multiple users. Each user can have a separate user storage that may be encrypted. The computing device boots as a system user to a login screen. A first student user enters user credentials into the login screen. The computing device can reboot the user-space processes, while leaving the kernel running, rebooting the computing device as the first student user. When the first student user logs out, data to be synchronized to, e.g., the cloud, can be synchronized for the first student user while a second student user is logged into the device.

Abstract: A method and apparatus of a device that changes the importance of a daemon process is described. In an exemplary embodiment, the device receives a message from a user process destined for daemon process, wherein the daemon process executes independently of the user process and the first daemon process communicates messages with other executing processes. The device further determines if the first message indicates that the importance of the first daemon process can be changed. If the first message indicates the importance of the first daemon process can be changed, the device changes the importance of the first daemon process. The device additionally forwards the first message to the first daemon process.

Abstract: Techniques are disclosed relating to securely storing data at a computing device that is managed by an external entity. In some embodiments, a computing device maintains a first file system volume having data that is accessible to a user of the computing device and that is not managed by an entity external to the computing device. The computing device receives, from the entity external, a first request to configure the computing device to store data that is accessible to the user and managed by the external entity. In response to the first request, the computing device creates a second distinct file system volume to store the data managed by the external entity. In response to a second request from the external entity, the computing device subsequently removes the second file system volume.
