[Xen-devel] [PATCH v2 0/2] xen/locks: fix preempt disabling in lock handling

Posted by Juergen Gross 3 weeks ago
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.

Changes in V2:
- move the preempt_[dis|en]able() calls

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