Even though the RFW_* flags were first introduced in Linux 4.6, they
could not be used with aio until 4.12 where the aio_rw_flags field was
added to struct iocb (9830f4be159b "fs: Use RWF_* flags for AIO
operations"). Correct the version for each flag.

Is the version number you propose correct? When I check:

$ git describe --contains 9830f4be159b
v4.13-rc1~70^2~30

So, should be 4.13, no?

Thanks,

Michael
