Name:Check whether this bio extends beyond the end of the device or partition.* This may well happen - the kernel calls bread() without checking the size of* the device, e.g., when mounting a file system.
Proto:static inline int bio_check_eod(struct bio *bio, sector_t maxsector)
Type:int
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct bio * | bio | |
| sector_t | maxsector |
| 826 | nr_sectors = bio_sectors(bio) |
| 828 | If nr_sectors && maxsector && ( nr_sectors > maxsector || device address in 512 byte sectors > maxsector - nr_sectors ) Then |
| 831 | handle_bad_sector(bio, maxsector) |
| 832 | Return -EIO |
| 834 | Return 0 |
