* Once the synctask is done and the discarding zthr is awake, we discard
* the checkpointed data over multiple TXGs by having the zthr prefetching
* entries from vdev_checkpoint_sm and then starting a synctask that places
- * them as free blocks in to their respective ms_allocatable and ms_sm
+ * them as free blocks into their respective ms_allocatable and ms_sm
* structures.
