Dear All,
This is a proposal for adding O_DIRECT support into JDK 9 for reading/writing
from/to a file on Linux platform. O_DIRECT is a file-open flag to pass to OPEN
(2). It tries to minimize cache effects of the I/O to and from this file. File
I/O is done directly to/from user-space buffers. Please refer to
http://man7.org/linux/man-pages/man2/open.2.html for more details.
FIS/FOS/RAF doesn't seem the right place for this. Have you looked at
using extended open options with FileChannel instead?
