Usage of direct IO with virtual threads

[Andrey Lomakin]

Hi guys.

Could you clarify is it OK to
use com.sun.nio.file.ExtendedOpenOption#DIRECT  open option with virtual
threads or in other words, will reading/writing to the file which uses
direct IO be converted into the non-blocking call ?

And second question, what is the general status of integration of
FileChannel API with virtual threads, if I , for example, perform fsync,
will it be also converted into non-blocking call at leas on platforms which
theoretically support such possibilities (like io_uring

?
