Descriptions
In the Linux kernel, the following vulnerability has been resolved: ftrace: Add cond_resched() to ftrace_graph_set_hash() When the kernel contains a large number of functions that can be traced,
the loop in ftrace_graph_set_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.
