函数名称：bpf_check_tail_call

函数原型：static int bpf_check_tail_call(const struct bpf_prog *fp)

返回类型：int

参数：

类型参数名称
const struct bpf_prog *fp
1743  aux等于 Auxiliary fields
1746  以i小于used_map_cnt循环
1747  map等于used_maps[i]
1750  如果map_type不等于BPF_MAP_TYPE_PROG_ARRAY则继续下一循环
1753  array等于container_of - cast a member of a structure out to the containing structure*@ptr: the pointer to the member.*@type: the type of the container struct this is embedded in.*@member: the name of the member within the struct.(map, structbpf_array, map)
1754  如果非bpf_prog_array_compatible(array, fp)则返回:负EINVAL
1758  返回:0
