In case spufs_fill_dir() fails only put_spu_context() 
gets called for cleanup and the acquired mm_struct never gets freed.

Sebastian,

Good catch. However - could we do the mmput in the context destroy path 
instead?

Also, you're probably better-off sending patches inline. It makes 
commenting on the patch much easier for some mailers.

Cheers,


Jeremy
