Proto:void __blk_complete_request(struct request *req)

Type:void

Parameter:

Type	Parameter	Name
struct request *	req

q = q

97

ccpu = cpu

99

bool shared = false

101

BUG_ON(!complete)

103

local_irq_save(flags)

104

cpu = smp_processor_id()

109

If Determine whether a bit is set(complete on same CPU-group , & * various queue flags, see QUEUE_* below) && ccpu != -1 Then

110

If Not Determine whether a bit is set(rce complete on same CPU , & * various queue flags, see QUEUE_* below) Then shared = cpus_share_cache(cpu, ccpu)

112

Else ccpu = cpu

123

If ccpu == cpu || shared Then

125

126

list = this_cpu_ptr( & blk_cpu_done)

127

list_add_tail - add a new entry*@new: new entry to be added*@head: list head to add it before* Insert a new entry before the specified head.* This is useful for implementing queues.

135

If next == ipi_list Then This function must run with irqs disabled!

137

Else if raise_blk_irq(ccpu, req) Then Go to do_local

140
