Hi Onkar,
This seems to be in conjunction with the field i_sync_tid in the inode
structure. They are used to store the transaction id of the journal.
Depending on what system call you use fsync() or fdatasync() to flush
the contents of your file, it will use i_sync_tid or i_datasync_tid
and will commit the appropriate transaction to disk.
Hope that helps...
