In the Linux kernel, the following vulnerability has been resolved:[EOL][EOL]ftrace: Fix softlockup in ftrace_module_enable[EOL][EOL]A soft lockup was observed when loading amdgpu module.[EOL]If a module has a lot of tracable functions, multiple calls[EOL]to kallsyms_lookup can spend too much time in RCU critical[EOL]section and with disabled preemption, causing kernel panic.[EOL]This is the same issue that was fixed in[EOL]commit d0b24b4e91fc ("ftrace: Prevent RCU stall on PREEMPT_VOLUNTARY[EOL]kernels") and commit 42ea22e754ba ("ftrace: Add cond_resched() to[EOL]ftrace_graph_set_hash()").[EOL][EOL]Fix it the same way by adding cond_resched() in ftrace_module_enable.
