1 | Subject: Check for device resize when rescanning partitions |

| 7 | Check for device resize in the rescan_partitions() routine. If the device | |
| 8 | has been resized, the bdev size is set to match. The rescan_partitions() | |
| 9 | routine is called when opening the device and when calling the | |
| 10 | BLKRRPART ioctl. | |

| 12 | Adapted for SLES11, based on the original commit. | |
