Abstract: The present invention provides a computer implemented method and apparatus for unmounting file systems from a plurality of file servers. The method comprises of issuing an unmount command targeting a file system of a first server among the plurality of file servers. The timeout period is then expired without receiving an unmount acknowledgement associated with the unmount command. Thus, the timeout period is associated with an allowable time for the file system to acknowledge unmounting. In response to expiring the timeout period, a ping is transmitted to the first server among the plurality of file servers. The ping timeout then expires based on a failure to receive a ping acknowledgment corresponding to the ping. This action marks the first server for a later retry of unmounting to form a marked set based on the first server.

Abstract: Methods, systems, and computer program products for managing electronic delegation messages. Embodiments of the present disclosure allow a user of an electronic messaging system to designate messages as a delegation messages. Further embodiments facilitate tracking and management of the delegation corresponding to the message. The delegation functionality may be incorporated into existing electronic messaging systems. The invention includes a method including accepting from a user a designation of an electronic message as a delegation by the user. The user may designate the electronic message as a delegation by interacting with a user interface for an electronic message system modified to recognize the designation. The electronic message may be an email message, an instant message, or a text message. The interface may be a graphical user interface. Designating the message may be accomplished by selecting an icon, entering text, and so on.

Abstract: A computer implemented method, apparatus, and computer program product for using trusted user space pages. A kernel accesses a set of trusted pages in user space. The set of trusted user space pages are read-only pages in user mode. Each trusted user space page in the set of trusted user space pages is set to be a readable and writeable page by the kernel. Data captured by the kernel is saved directly to a trusted user space page in the set of trusted user space pages.
