Type:void

Parameter:

Type	Parameter	Name
struct static_key *	key

stop = __stop___jump_table

794

If static_key_linked(key) Then

795

__jump_label_mod_update(key)

796

Return

799

Even if we don't have any preemption, we need preempt disable/enable* to be barriers, so that we don't have things like get_user/put_user* that can cause faults and scheduling migrate into our preempt-protected* region.()

mod = __module_address - get the module which contains an address.*@addr: the address.* Must be called with preempt disabled or module mutex held so that* module doesn't get freed during this.

801

If mod Then stop = jump_entries + num_jump_entries

803

preempt_enable()

805

entry = static_key_entries(key)

807

If entry Then __jump_label_update(key, entry, stop, Values used for system_state. Ordering of the states must not be changed* as code checks for <, <=, >, >= STATE. < SYSTEM_RUNNING)
