Ok, so there is no such flag over the NFSv3 XDR protocol,
however:
The NFSv3 SERVER (for which Andrea made his patch)
actually MUST open local files with O_LARGEFILE
flag set. (Otherwise e.g. EXT2 may reject the open.)
The NFSv3 CLIENT code must do post-open verification,
that if the opened file has size exceeding 2G-1, and
O_LARGEFILE flag is not set, the opened file must be
closed, and caller must be informed of the rejection
with -EFBIG status.
(If possible, do that size verification before open.)
Am I making any sense ?
