sendfile -EOVERFLOW on AMD64

[Jan Kasprzak]

	Hello,

today (after the Fedora Core 2 release) I have discovered that my FTP
server (running AMD64) cannot correctly send the >2GB files using sendfile().
The server is ProFTPd, and the strace looks like this:

[...]
alarm(288)                              = 0
sendfile(14, 11, [139377240], 4231263656) = 2008106407
alarm(0)                                = 117
alarm(117)                              = 0
alarm(0)                                = 117
alarm(117)                              = 0
sendfile(14, 11, [2147483647], 2223157249) = -1 EOVERFLOW (Value too large for defined data type)

The image (FC2-i386-DVD.iso) has 4370640896 bytes. The FTP server is native
x86_64 binary, not a 32-bit one.

Thanks for any hints.
