It's not that the patch is incorrect, but: 1) This is an error path, surely we do not care about caching in that case. If it's often hit, then the application would be buggy. 2) If you're going to add an io_free_ifd() helper, then at least use it for the normal case too that still open-codes it. -- Jens Axboe
