[haiku-development] reading/writing negative positions

Hi,

I noticed that neither fd.c nor vfs.cpp do anything to prevent read and write 
calls at positions < 0.

However, file_seek doesn't support negative positions and will return an error.

The read/write calls get through into the file system or raw device.

Wouldn't it be better to validate the position inside fd.c instead of passing 
them to the lower layers?

regards
Marcus
