Filesystems are generally updated in a serial fashion:
1. Update MetaData
2. Update FileData
3. Sync...  (optional)

Is it possible to instruct the FS to delay metadata update until after a
filedata sync?
Like:
1. Buffer MetaData
2. Update FileData
3. Sync
4. Update MetaData
5. Sync...      (optional)

Ext3 offers this as an ordered mode, but could this be done on a lower level
as in bdflush?
