[PATCH] spufs: check for proper file pointer in sys_spu_run
Only checking for SPUFS_MAGIC is not reliable, because it might not be unique in theory. Worse than that, we accidentally allow spu_run to be performed on any file in spufs, not just those returned from spu_create as intended. Noticed by Al Viro.
