函数名称：atari_partition

函数原型：int atari_partition(struct parsed_partitions *state)

返回类型：int

参数：

类型参数名称
struct parsed_partitions *state
43  part_fmt等于0
50  如果bdev_logical_block_size(bdev)不等于512则返回:0
53  rs等于read_part_sector(state, 0, & sect)
54  如果非rs则返回:负1
58  hd_size等于i_size右移9位
59  如果非check if a partition entry looks valid -- Atari format is assumed if atleast one of the primary entries is ok this way ( & part[0], hd_size)且非check if a partition entry looks valid -- Atari format is assumed if atleast one of the primary entries is ok this way ( & part[1], hd_size)且非check if a partition entry looks valid -- Atari format is assumed if atleast one of the primary entries is ok this way ( & part[2], hd_size)且非check if a partition entry looks valid -- Atari format is assumed if atleast one of the primary entries is ok this way ( & part[3], hd_size)则
68  put_dev_sector(sect)
69  返回:0
72  pi等于part[0]
73  长字符串拼接
74  以pi小于part[4]且slot小于limit循环
79  如果非 0: active; bit 7: bootable 按位与1的值则继续下一循环
82  如果内存比较不等于0则
84  put_partition(state, slot, be32_to_cpu(start of partition ), be32_to_cpu(length of partition ))
86  继续下一循环
90  part_fmt等于1
92  长字符串拼接
93  partsect等于extensect等于be32_to_cpu(start of partition )
94  当1循环
95  xrs等于read_part_sector(state, partsect, & sect2)
96  如果非xrs则
103  如果非 0: active; bit 7: bootable 按位与1的值则
109  put_partition(state, slot, partsect + be32_to_cpu(start of partition ), be32_to_cpu(length of partition ))
113  如果非 0: active; bit 7: bootable 按位与1的值则
115  put_dev_sector(sect2)
116  退出
118  如果内存比较不等于0则
124  partsect等于be32_to_cpu(start of partition )加extensect
125  put_dev_sector(sect2)
126  如果slot先自加恒等于limit则
131  长字符串拼接
134  如果part_fmt不等于1则
135  pi等于 info for ICD-partitions 5..12 [0]
137  如果OK_id("GEM", "BGM", "XGM", or other )则
138  长字符串拼接
139  以pi小于 info for ICD-partitions 5..12 [8]且slot小于limit循环
148  长字符串拼接
152  put_dev_sector(sect)
154  长字符串拼接
156  返回:1
