Type:void

Parameter:Nothing

64

crash_vmclear_fn * do_vmclear_operation = NULL

66

_read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other

67

do_vmclear_operation = fetch RCU-protected pointer for dereferencing(This is used to VMCLEAR all VMCSs loaded on the* processor. And when loading kvm_intel module, the* callback function pointer will be assigned.* protected by rcu.)

68

If do_vmclear_operation Then do_vmclear_operation()

70

_read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
