Description:
Falcon uses O_DIRECT or O_SYNC when opening files. On Solaris it will use O_SYNC as O_DIRECT is not supported. It should support the use of directio(..., DIRECTIO_ON) as a hint on Solaris.

How to repeat:
NA

Suggested fix:
NA

We do not work on Falcon storage engine now, so I doubt this feature will be implemented.
