I did some research about it and looks like we're not suppose to use
O_DIRECT but madvice or posix_fadvice.
One example of it is GNOME-VFS where they do:
#v+
static GnomeVFSResult
do_forget_cache (GnomeVFSMethod *method,
GnomeVFSMethodHandle *method_handle,
GnomeVFSFileOffset offset,
GnomeVFSFileSize size)
{
FileHandle *file_handle;
g_return_val_if_fail (method_handle != NULL, GNOME_VFS_ERROR_INTERNAL);
file_handle = (FileHandle *) method_handle;
#ifdef HAVE_POSIX_FADVISE
posix_fadvise (file_handle->fd, offset, size, POSIX_FADV_DONTNEED);
#endif
return GNOME_VFS_OK;
}
#v-
Once I have time I'll see if I can prepare a patch for testing using
this idea.
