CFQ I/O scheduler - per thread?

["Siddharth Taneja" <siddharth.taneja@xxxxxxxxx>]

Hi,

I wanted to know if the CFQ scheduler maintains queues per threads. From the source code it does not seem so and also 'ionice' only allows setting priorities on a per process basis. Am I right? If so, do we know if the implementation would be extended on a per thread basis?

Thanks
