Hi Ingo,
This series has some updates to Xen's spinlock implementation, including adding a set of performance measurements in debugfs.
The series consists of: - correctly deal with a spinlock in an interrupt handler interrupting another spinlock spinning on a lock. [2.6.27 bugfix] - Add Xen debugfs support, including performance metrics for spinlocks, multicalls and mmu operations. - Allow interrupts to be enabled while spinning (blocking) for a lock - Measure time spinlocks spend blocked
Thanks, J
