BugLink: http://bugs.launchpad.net/bugs/1761674 == SRU Justification == IBM reported this bug due to a regression introduced by mainline commit 94232a4332de. IBM has requested this SAUCE backport to resolve this regression in Artful and Xenial. With Bionic and v4.15, the rwlock code has been rewritten. See upstream git commit: eb3b7b848fb3 ("s390/rwlock: introduce rwlock wait queueing"). Since the upstream code has been rewritten there also won't be an upstream git commit id available which contains the attached fix. Artful also requires this fix, but it's backport is differant. It will be sent in another SRU request. == Fix == UBUNTU: SAUCE: (no-up) s390: fix rwlock implementation == Regression Potential == Low. The backport was written and tested by IBM. It is specific 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.
