Subject: [PATCH 1/2] AIO: Fix reference counting in io_cancel and aio_cancel_all

io_cancel() and aio_cancel_all() have inconsistent reference counting 
(ki_users field of struct kiocb) which leads to unkillable processes upon  
io_cancel() or io_destroy() syscalls. This patch fixes the undesired behavior.

Regards, Sergey Temerkhanov, Cifronic ZAO
