This fixes a bug introduced by mainline commit 0da9581ddb0f. The symptom of the bug is Failing transmissions on af_iucv HiperTransport socket. Bionic also needs this patch, but it does not require a backport, so it will be SRU'd separately. == Fix == ce28867fd20c ("s390/qeth: don't clobber buffer on async TX completion") == Regression Potential == Low. Limited to s390. == Test Case == A test kernel was built with this patch and tested by the original bug reporter. The bug reporter states the test kernel resolved the bug.
