120 help
121 This kernel feature is useful for number crunching applications
122 that may need to compute untrusted bytecode during their
123 execution. By using pipes or other transports made available to
124 the process as file descriptors supporting the read/write
125 syscalls, it's possible to isolate those applications in
126 their own address space using seccomp. Once seccomp is
127 enabled via /proc/<pid>/seccomp, it cannot be disabled
128 and the task is only allowed to execute a few safe syscalls
129 defined by each seccomp mode.

236 Select the kernel logical page size. Increasing the page size
237 will reduce software overhead at each page boundary, allow
238 hardware prefetch mechanisms to be more effective, and allow
239 larger dma transfers increasing IO efficiency and reducing
240 overhead. However the utilization of memory will increase.
241 For example, each cached file will using a multiple of the
242 page size to hold its contents and the difference between the
243 end of file and the end of page is wasted.
