and indeed, sys_pwrite in fs/read_write.c doesn't seem to do
everything that lseek() followed by write() would do, in particular it
doesn't call the file's file->f_op->llseek procedure. I don't know if
that's the problem; I can get more details from this guy about what
kind of file he was using if necessary.
Comments?
