函数名称：find_syscall_meta

函数原型：static __init struct syscall_metadata *find_syscall_meta(unsigned long syscall)

返回类型：struct syscall_metadata

参数：

类型参数名称
unsigned longsyscall
90  start等于__start_syscalls_metadata
91  stop等于__stop_syscalls_metadata
92  Lookup an address* - modname is set to NULL if it's in the kernel.* - We guarantee that the returned name is valid until we reschedule even if.* It resides in a module.* - We also guarantee that modname will be valid until rescheduled.
94  如果arch_syscall_match_sym_name(str, "sys_ni_syscall")则返回:NULL
97  以start小于stop循环
98  如果name且arch_syscall_match_sym_name(str, name)则返回:start
101  返回:NULL
