In the Linux kernel, the following vulnerability has been resolved:
ftrace: Add condresched() to ftracegraphsethash()
When the kernel contains a large number of functions that can be traced, the loop in ftracegraphset_hash() may take a lot of time to execute. This may trigger the softlockup watchdog.
Add cond_resched() within the loop to allow the kernel to remain responsive even when processing a large number of functions.
This matches the cond_resched() that is used in other locations of the code that iterates over all functions that can be traced.
