  92. This kernel feature is useful for number crunching applications
  93. that may need to compute untrusted bytecode during their
  94. execution. By using pipes or other transports made available to
  95. the process as file descriptors supporting the read/write
  96. syscalls, it's possible to isolate those applications in
  97. their own address space using seccomp. Once seccomp is
  98. enabled via /proc/<pid>/seccomp, it cannot be disabled
  99. and the task is only allowed to execute a few safe syscalls
  100. defined by each seccomp mode.

  140. access directly, without having to set up a kernel virtual mapping.

  186. Select the kernel logical page size. Increasing the page size
  187. will reduce software overhead at each page boundary, allow
  188. hardware prefetch mechanisms to be more effective, and allow
  189. larger dma transfers increasing IO efficiency and reducing
  190. overhead. However the utilization of memory will increase.
  191. For example, each cached file will using a multiple of the
  192. page size to hold its contents and the difference between the
  193. end of file and the end of page is wasted.
