func (T) FlushBufs ¶

func (t T) FlushBufs(ctx context.Context) error

FlushBufs drops the buffers of the device and of the devices it rests on, as the paths of a multipath device.

A write through a device, as a signature wiped or a superblock zeroed, does not reach the buffers of the devices below it, and blkid reads those: it goes on reporting what was erased, under the name of every path, until they are dropped.
