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