Package: glibc-source Version: 2.24-18 Severity: normal Tags: patch Dear glibc maintainers,
I think it is a good idea to disable lock elision on glibc for ppc64el on 'sid' for now. The motivation for this change is basically two: 1) There are some Hardware Transactional Memory[1] changes on POWER9 and that I would prefer to not trust at this moment for such an important package. 2) There are some hard to debug bugs that is being affected by this feature[2], so, disabling it until we address all these bugs. We should re-enable this feature once the two concerns above be addressed.
