Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: scsi: hisi_sas: Add cond_resched() for no forced preemption model For no forced preemption model kernel, in the scenario where the expander is connected to 12 high performance SAS SSDs, the following call trace may occur: [ 214.409199][ C240] watchdog: BUG: soft lockup - CPU#240 stuck for 22s!

In the performance test scenario, function irq_wait_for_interrupt() will always return 0 if lots of interrupts occurs and the CPU will be continuously consumed. As a result, the CPU cannot run the watchdog thread. When the watchdog time exceeds the specified time, call trace occurs. To fix it, add cond_resched() to execute the watchdog thread.
