-1.6 What is a marker_pid ?
---------------------------
-
-The marker_pid helps manage cpuset changes safely from user space.
-
-The interface presented to user space for cpusets uses system wide
-numbering of CPUs and Memory Nodes.   It is the responsibility of
-user level code, presumably in a library, to present cpuset-relative
-numbering to applications when that would be more useful to them.
-
-However if a task is moved to a different cpuset, or if the 'cpus' or
-'mems' of a cpuset are changed, then we need a way for such library
-code to detect that its cpuset-relative numbering has changed, when
-expressed using system wide numbering.
-
-The kernel cannot safely allow user code to lock kernel resources.
-The kernel could deliver out-of-band notice of cpuset changes by
-such mechanisms as signals or usermodehelper callbacks, however
-this can't be synchronously delivered to library code linked in
-applications without intruding on the IPC mechanisms available to
-the app.  The kernel could require user level code to do all the work,
-tracking the cpuset state before and during changes, to verify no
-unexpected change occurred, but this becomes an onerous task.
-
-The "marker_pid" cpuset field provides a simple way to make this task
-less onerous on user library code.  A task writes its pid to a cpusets
-"marker_pid" at the start of a sequence of queries and updates,
-and check as it goes that the cpusets marker_pid doesn't change.
-The pread(2) system call does a seek and read in a single call.
-If the marker_pid changes, the user code should retry the required
-sequence of operations.
-
-Anytime that a task modifies the "cpus" or "mems" of a cpuset,
-unless it's pid is in the cpusets marker_pid field, the kernel zeros
-this field.
-
-The above was inspired by the load linked and store conditional
-(ll/sc) instructions in the MIPS II instruction set.
