函数名称：btf_int_seq_show

函数原型：static void btf_int_seq_show(const struct btf *btf, const struct btf_type *t, u32 type_id, void *data, u8 bits_offset, struct seq_file *m)

返回类型：void

参数：

类型参数名称
const struct btf *btf
const struct btf_type *t
u32type_id
void *data
u8bits_offset
struct seq_file *m
1510  int_data等于btf_type_int(t)
1511  encoding等于BTF_KIND_INT is followed by a u32 and the following* is the 32 bits arrangement:(int_data)
1512  sign等于encoding按位与Attributes stored in the BTF_INT_ENCODING
1513  nr_bits等于BTF_INT_BITS(int_data)
1515  如果bits_offset或BTF_INT_OFFSET(int_data)或BITS_PER_BYTE_MASKED(nr_bits)则
1517  btf_int_bits_seq_show(btf, t, data, bits_offset, m)
1518  返回
1522  当:nr_bits恒等于128
1523  btf_int128_print(m, data)
1524  退出
1525  当:nr_bits恒等于64
1526  如果sign则seq_printf(m, "%lld", * (s64 * )data)
1528  否则seq_printf(m, "%llu", * (u64 * )data)
1530  退出
1531  当:nr_bits恒等于32
1532  如果sign则seq_printf(m, "%d", * (s32 * )data)
1534  否则seq_printf(m, "%u", * (u32 * )data)
1536  退出
1537  当:nr_bits恒等于16
1538  如果sign则seq_printf(m, "%d", * (s16 * )data)
1540  否则seq_printf(m, "%u", * (u16 * )data)
1542  退出
1543  当:nr_bits恒等于8
1544  如果sign则seq_printf(m, "%d", * (s8 * )data)
1546  否则seq_printf(m, "%u", * (u8 * )data)
1548  退出
1549  默认
1550  btf_int_bits_seq_show(btf, t, data, bits_offset, m)
