| 4 | Subject: [PATCH] md: allow setting newly added device to 'in_sync' via sysfs. | |
| 5 | ||
| 6 | When adding devices to an active array via sysfs, there is currently | |
| 7 | no way to mark a device as 'in-sync' which is useful when | |
| 8 | incrementally assembling an array. | |
| 9 | ||
| 10 | So add that option. | |
