Not true.  Check generic_file_buffered_write() and generic_file_direct_write()
- that's where it's normally stored into iocb->ki_pos (via *ppos).  And yes,
I agree that the damn thing is obfuscated to hell and back - other commits
in my local tree kill 'ppos' arguments of __generic_file_aio_write() and
generic_file_buffered_write() (equal to &iocb->ki_pos for all call sites),
which makes it a bit easier to keep track of.  Will push that part of
queue into vfs.git#iov_iter today...
