A computer implementing a kernel, the computer including: a processor that is configured to run processes in kernel mode and to run other processes not in kernel mode, wherein the processor is configured to run in the kernel mode the following processes: (a) determining selection parameters that relates to a system call requesting an operation by a hardware device, by processing information of the system call; (b) deterministically selecting a single data-structure element (DSE) of a data-structure in response to a type of the system call, to at least one other determined selection parameter, and to a status of an activity flag included in the DSE that indicates an availability of the DSE for selection; wherein the selecting includes selecting a DSE that includes an activity flag that indicates that the DSE is available for selection; wherein at least one DSE of the data-structure is an inactive DSE that includes an activity flag indicating that the inactive DSE is not available for selection; (c) modifying an activity flag of at least one DSE of the data-structure, in response to activeness instructions stored in the DSE selected; (d) assigning a priority to the system call in response to a content of the DSE selected; and (e) selectively enabling fulfillment of the operation by the hardware device, in response to the priority assigned to the system call.
