Subject: [PATCH 0/2] mutex: Modifications to mutex_spin_on_owner

This patchset contains a few modifications to mutex_spin_on_owner().
The first patch makes the optimistic spinner continue spinning whenever
the owner changes, and the second patch refactors mutex_spin_on_owner()
to micro optimize the code as well as make it simpler.

Jason Low (2):
  mutex: In mutex_spin_on_owner(), return true when owner changes
  mutex: Refactor mutex_spin_on_owner
