[PATCH v2 0/2] xen/locking: fix and enhance lock debugging

Posted by Juergen Gross 3 years, 5 months ago

This small series fixes two issues with spinlock debug code and adds
lock debug code to rwlocks in order to catch IRQ violations.

Juergen Gross (2):
  xen/spinlocks: spin_trylock with interrupts off is always fine
  xen/rwlock: add check_lock() handling to rwlocks
