After some thinking I went back to the original version of your patch. For justification see 46f49b7a223ac7493e7cf619fb583d11edefc2c2: "When copy_to/from_user fails in the middle of transfer we should not report to the user that read/write partially succeeded but rather report -EFAULT right away, so that application will know that it got its buffers all wrong. If application messed up its buffers we can't trust the data fetched from userspace and successfully written to the device or if data read from the device and transferred to userspace ended up where application expected it to end."
