121 - Each task in the system is attached to a cpuset, via a pointer
141 - in init/main.c, to initialize the root cpuset at system boot.
147 - in the mbind and set_mempolicy system calls, to mask the requested
154 new system calls are added for cpusets - all support for querying and
155 modifying cpusets is via this cpuset file system.
167 Each cpuset is represented by a directory in the cgroup file system
186 New cpusets are created using the mkdir system call or shell
192 a large system into nested, dynamically changeable, "soft-partitions".

201 Such management of a system "in the large" integrates smoothly with

236 space. This enables configuring a system so that several independent
237 jobs can share common kernel data, such as file system pages, while
278 the system load imposed by a batch scheduler monitoring this
306 kernel allocates pages for the file system buffers and related in
311 the kernel will spread the file system buffers (page cache) evenly
316 then the kernel will spread some file system related slab caches,
