[Bug 1563784] Re: S390: glibc should not be configured with lock elision.

[Adam Conrad]

What's wrong with the s390x lock elision implementation that makes it
fundamentally worse than other architectures?  This is a pretty strange
request, given the obvious benefits of lock elision.

  Hi,

  The current glibc for s390 is configured with --enable-lock-elision.
  This could lead to an overall performance regression compared to locks without transactions.
  Please disable lock-elsion for s390.
