Details

In the Linux kernel, the following vulnerability has been resolved:

schedext: Fix invalid irq restore in scxops_bypass()

While adding outer irqsave/restore locking, 0e7ffff1b811 ("scx: Fix raciness in scxopsbypass()") forgot to convert an inner rqunlockirqrestore() to rq_unlock() which could re-enable IRQ prematurely leading to the following warning:

rawlocalirqrestore() called with IRQs enabled WARNING: CPU: 1 PID: 96 at kernel/locking/irqflag-debug.c:10 warnbogusirqrestore+0x30/0x40 ...

Drop the stray _irqrestore().
