|
|
|
===========
|
|
|
|
|
|
|
|
This ioctl call returns the number of uncorrected blocks detected by the
|
|
|
|
device driver during its lifetime. For meaningful measurements, the
|
|
|
|
increment in block count during a specific time interval should be
|
|
|
|
calculated. For this command, read-only access to the device is
|
|
|
|
sufficient.
