arch_uprobe_post_xol

Name:Called after single-stepping. To avoid the SMP problems that can* occur when we temporarily put back the original opcode to* single-step, we single-stepped a copy of the instruction.* This function prepares to resume execution after the single-step.

Proto:int arch_uprobe_post_xol(struct arch_uprobe *auprobe, struct pt_regs *regs)

Type:int

Parameter:

Type	Parameter	Name
struct arch_uprobe *	auprobe
