函数名称:s_pmbr_valid(): test Protective MBR for validity*@mbr: pointer to a legacy mbr structure*@total_sectors: amount of sectors in the device* Description: Checks for a valid protective or hybrid* master boot record (MBR)
函数原型:static int is_pmbr_valid(legacy_mbr *mbr, sector_t total_sectors)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
legacy_mbr * | mbr | |
sector_t | total_sectors |
176 | sz等于0 |
179 | 如果非mbr或le16_to_cpu(signature)不等于MSDOS_MBR_SIGNATURE则转到:done |
183 | ret等于pmbr_part_valid( & partition_record[i]) |
184 | 如果ret恒等于GPT_MBR_PROTECTIVE则 |
191 | 转到:check_hybrid |
195 | 如果ret不等于GPT_MBR_PROTECTIVE则转到:done |
197 | check_hybrid : |
198 | 以i小于4循环如果 EFI and legacy non-EFI OS types 不等于EFI_PMBR_OSTYPE_EFI_GPT且 EFI and legacy non-EFI OS types 不等于0x00则 |
202 | ret等于GPT_MBR_HYBRID |
216 | 如果ret恒等于GPT_MBR_PROTECTIVE则 |
218 | 如果sz不等于total_sectors减1且sz不等于0xFFFFFFFF则pr_debug("GPT: mbr size in lba (%u) different than whole disk (%u).\n", sz, min_t - return minimum of two values, using the specified type*@type: data type to use*@x: first value*@y: second value(uint32_t, total_sectors - 1, 0xFFFFFFFF)) |
223 | done : |
224 | 返回:ret |
名称 | 描述 |
