[Xen-devel] [PATCH 0/2] xen/locks: fix preempt disabling in lock handling

[Juergen Gross <jgross@xxxxxxxx>]

Xen's rwlocks don't disable preemption at all, while spinlocks are
doing it only after obtaining the lock.

While not really critical, it is wrong.

This series fixes that.

Juergen Gross (2):
  xen/rwlocks: call preempt_disable() when taking a rwlock
  xen/spinlocks: fix placement of preempt_[dis|en]able()
