call_srcu

Name:Enqueue an SRCU callback on the specified srcu_struct structure,* initiating grace-period processing if it is not already running.

Proto:void call_srcu(struct srcu_struct *ssp, struct callback_head *rhp, rcu_callback_t func)

Type:void

Parameter:

Type	Parameter	Name
struct srcu_struct *	ssp
struct callback_head *	rhp
rcu_callback_t	func

next = NULL

165

local_irq_save(flags)

166

Pending callbacks: Tail. = rhp

167

Pending callbacks: Tail. = next

168

local_irq_restore(flags)

If Not READ_ONCE( GP workqueue running? ) Then

170

If Value is more likely to compile time(srcu_init_done) Then schedule_work - put work task in global workqueue*@work: job to be done* Returns %false if @work was already on the kernel-global workqueue and* %true otherwise

172

Else if list_empty - tests whether a list is empty*@head: the list to test. Then list_add - add a new entry*@new: new entry to be added*@head: list head to add it after* Insert a new entry after the specified head.* This is good for implementing stacks.
