Description The issue arises when the kernel contains a large number of functions that can be traced. The loop in ftrace graph set hash() may take a significant amount of time to execute, potentially triggering the softlockup watchdog. To address this, cond resched() has been added within the loop to allow the kernel to remain responsive even when processing a large number of functions.
