Christoph Hellwig 486acd4850 [CELL] spufs: rework list management and associated locking ... This sorts out the various lists and related locks in the spu code. In detail: - the per-node free_spus and active_list are gone. Instead struct spu gained an alloc_state member telling whether the spu is free or not - the per-node spus array is now locked by a per-node mutex, which takes over from the global spu_lock and the per-node active_mutex - the spu_alloc* and spu_free function are gone as the state change is now done inline in the spufs code. This allows some more sharing of code for the affinity vs normal case and more efficient locking - some little refactoring in the affinity code for this locking scheme Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>		18 years ago
