The patch titled Subject: sgi-xp: nested calls to spin_lock_irqsave() has been removed from the -mm tree. Its filename was sgi-xp-nested-calls-to-spin_lock_irqsave.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Dan Carpenter <dan.carpenter@xxxxxxxxxx> Subject: sgi-xp: nested calls to spin_lock_irqsave() The code here has a nested spin_lock_irqsave(). It's not needed since IRQs are already disabled and it causes a problem because it means that IRQs won't be enabled again at the end. The second call to spin_lock_irqsave() will overwrite the value of irq_flags and we can't restore the proper settings.
