Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix spin_unlock_irqrestore() called with IRQs enabled Fix missuse of spin_lock_irq()/spin_unlock_irq() when spin_lock_irqsave()/spin_lock_irqrestore() was hold. This was discovered through the lock debugging, and the corresponding log is as follows: raw_local_irq_restore() called with IRQs enabled WARNING: CPU: 96 PID: 2074 at kernel/locking/irqflag-debug.c:10 warn_bogus_irq_restore+0x30/0x40 ...
