The file is in the DAX (cpu direct access) state.
DAX state attempts to
minimize software cache effects for both I/O and memory mappings of this file.
It requires a file system which has been configured to support DAX.
-.PP
+.IP
DAX generally assumes all accesses are via CPU load / store instructions
which can minimize overhead for small accesses,
but may adversely affect CPU utilization for large transfers.
-.PP
+.IP
File I/O is done directly to/from user-space buffers and memory mapped I/O may
be performed with direct memory mappings that bypass the kernel page cache.

While the DAX property tends to result in data being transferred synchronously,
it does not give the same guarantees as the
.B O_SYNC
flag (see
.BR open (2)),
where data and the necessary metadata are transferred together.

A DAX file may support being mapped with the

flag, which enables a
