* When remounting a filesystem read-only or freezing the filesystem,
* we have two phases to execute. This first phase is syncing the data
* before we quiesce the fielsystem, and the second is flushing all the
* inodes out after we've waited for all the transactions created by
* the first phase to complete. The second phase uses SYNC_INODE_QUIESCE
* to ensure that the inodes are written to their location on disk
* rather than just existing in transactions in the log. This means
* after a quiesce there is no log replay required to write the inodes
* to disk (this is the main difference between a sync and a quiesce).
