| H A D | smpboot.h | f97f8f06 Mon Jul 16 05:42:36 CDT 2012 Thomas Gleixner <tglx@linutronix.de> smpboot: Provide infrastructure for percpu hotplug threads
Provide a generic interface for setting up and tearing down percpu
threads.
On registration the threads for already online cpus are created and
started. On deregistration (modules) the threads are stoppped.
During hotplug operations the threads are created, started, parked and
unparked. The datastructure for registration provides a pointer to
percpu storage space and optional setup, cleanup, park, unpark
functions. These functions are called when the thread state changes.
Each implementation has to provide a function which is queried and
returns whether the thread should run and the thread function itself.
The core code handles all state transitions and avoids duplicated code
in the call sites.
